Doesn't read DVD drive on laptop. Why doesn't the laptop see the disk in the drive? What to do if the disk is unreadable

Why doesn't the drive read?CDs or DVDs and at the most inopportune moment, when we urgently need the information on them, for example: coursework or a diploma.Or a less critical option: we borrowed a CD with movies and music from friends, came home and unfortunately realized that our DVD drive is not able to read the information on this CD, what should we do in this case? Wait to make a flying saucer out of a CD, we'll come up with something now. First of all, remember that many problems arise, including this one, which can be solved by simply restarting the computer. Friends, if this article does not help you, try looking for a solution in another .

Why doesn't the drive read?

• From the very beginning, inspect the surface of the CD to see if there are any scratches or dirty spots on it; if there are any, they should be removed with a soft cloth or cotton wool, without applying force, moving from the center of the disc to its edges.
• Note: Friends, the most important thing to know is that many quite serviceable, but capricious disk drives from well-known manufacturers sometimes do not read some stale disks that you stored somewhere, if they have very important information, you do not need to rub them with anything, this way you can make a disk not at all readable. In this case, just go to your friends and 100%, some drive will read your disk, then you just need to rewrite it onto a blank disc from a well-known manufacturer, which in turn will be read by your drive.
• If scratches are visible on the surface of the disk, you can try to polish them with a special tool; if there is no damage and the files on this CD were accessible an hour ago on another computer, then the problem is your drive.
• Maybe you have this problem all the time and your drive does not read CDs or DVDs from time to time, then it is better to replace it. Many times I read on the Internet about miracle products that allow you to clean the laser lens of a disk drive, do not believe it, and especially do not buy it.
  I saw on sale special discs that clean the lens of a DVD ROM from a very well-known company, but for some reason there was no information about such a disc on the official website of this manufacturer.
• Friends, if you decide to disassemble the DVD-CDRW drive and clean the lens (it rarely helps), then know that it is best to blow it with a blower, but under no circumstances wipe it with cotton wool (the fibers will stick); it is also risky to rub it with napkins or brushes and so on.
• They may also recommend you a cleaning disk, but unfortunately a real one is very difficult to find, and the one you buy in the subway will finish off your lens completely.

Over the course of my life, I have come across various disk drives, and some of them, from the very purchase itself, could not from time to time read or write information on DVD+R or DVD-R discs. Sometimes a DVD drive cannot read cheap discs, but branded discs work without problems. So you should know everything about your drive.

What I would like to advise is that when buying a computer, pay attention to all the components, including the disk drive, buy it from well-known and reputable companies, even if they are more expensive.

By the way, you shouldn’t focus your attention on the drive; in most of these cases, the problem lies in the CD or DVD that we carelessly stored.

So, there are small scratches on our CD and we can’t remove them in any way, what should we do?
I will give, for example, one very good and free program that solves such problems, and most importantly, I will show with a concrete example how to work with it. The program is called Non-Stop Copy, you can get it on the official website of the developer: Dmitry Sergeev http://dsergeyev.ru/programs/nscopy/ or on my Yandex.Disk.

If anyone wants to work with paid programs, please, below are links to articles on our site that provide examples of working with,.

In the article I gave a common example of copying a single file from damaged media, but if you need to restore a group of files, check out our article.

I'll start with a short introduction. A friend came to me and said: “Save me, DVD drive does not read I couldn’t download a CD with my daughter’s favorite movie on the Internet, I just picked up viruses.”

My friend has a weak level of Internet training; he works in a managerial position and the only thing he can’t do is find films on the Internet, no matter how long I taught him.

Well, okay, we look at the CD and see strong scratches on it, launch our program and insert the disc into the drive, click Select file and specify our DVD drive,

in my case it is called (D:)

According to a friend, we need a movie: "The NeverEnding Story 3". Let's highlight it; personally, I like the first part the most.

Let's talk to you about why the DVD drive doesn't read discs. Problems with DVD drives are something that almost every user will encounter at some point. In this article, we will figure out what could be the reasons why a DVD drive does not read discs and what to do in such a situation.

If your DVD drive doesn't read discs, don't rush to buy a new one! Discs may not play for a variety of reasons. The problem may not be a faulty drive at all.

If the DVD drive fails, there are many ways to restore it to functionality. Below we will look at these methods, and also tell you how you can reproduce scratched discs.

Determining the nature of the problem.

First of all, you need to determine the nature of the malfunction. The DVD drive may not read all discs at all, or only some. Check it. If some disks are still readable, then the problem is in the hardware. I will tell you how to solve it below.

First of all, we will talk about the disks themselves, or more precisely about the condition of the surface of the disks. And then we will try to return the drive to its former agility by removing software restrictions. If the operating system malfunctions, the drive may not read anything at all. By the way, there may or may not be the same problems with recording discs.

Damage to the disc surface.

In most cases, the reason when a DVD drive does not read discs lies in their problematic surface. That's where we'll start. If the CD/DVD media is very important to you, you can try restoring it. To do this, let's look at several ways.

Try wiping the disc gently with a dry, soft cloth. It is very important that you need to wipe across the paths, from the center to the edges. Under no circumstances should you wipe the disc in circles! In this way, we clean the disk from dirt. If it is not badly scratched, this will be enough to transfer files to your computer.

If the drive still does not read it, we try to polish it. To do this, apply a polish containing wax to the scratches and rub well with a soft cloth. At least we will be able to open the disk once to extract information from it onto the computer.

Then we install a special program on the computer that can be used to read the damaged disk, for example, the free Unstoppable Copier utility. When copying, this program tries to count damaged sectors several times and if it fails, skips them. Thus, you can copy from a disk to a computer, although not all the information, but most of it.

It is also possible that a problem occurred while writing the DVD RW, as a result of which the device does not read it. Most often, this situation can arise if the recording parameters are incorrectly set in the Alcohol 120% program. Try re-recording it or using another DVD media.

Remember what programs you installed recently, what games your children installed? Managers are often the cause of the problem. virtual disks, such as Alcohol 120% And Daemon Tools. Games can install virtual disks for their own needs, and they can conflict with each other. In some cases, the DVD drive does not read discs after installing a disc burning program Nero.

To make sure that this is the problem, the advice is simple - demolish these programs and look at the result. But deleting may not bring results unless you roll back to an earlier state of the system when everything was still working.

If everything works, then we dig into the problem in this direction: we try other analogues, other versions, leaving only what is necessary.

In the case of “alcohol”, try unchecking the program settings "Force other programs to detect disks as CD-ROM or DVD-ROM".

The second cause of the problem may be a driver glitch. To solve the problem we need "Device Manager".

To access Device Manager, go to “Control Panel -> System” or press hotkeys "Win + Pause" and on the left select "Device Manager".

After removing the above-mentioned software, virtual disk drives may still be present in the device manager in the section "DVD and CD-ROM drives". Delete them via the right-click menu, restart your computer and look at the result.

The following is what you can do:

• Go to the menu "View" and select "Show hidden devices".


• Find the driver in the device tree "SPTD" in the thread "Non-plug and play device drivers".


• Uninstall the driver and restart your computer.

This is all an inheritance from virtual disk drives.

If it doesn't help, move on. In chapter "IDE ATA/ATAPI controllers" Among two or four channels of the controller, you need to find the one to which the DVD drive is connected. These four channels may be called by different names, for example "Primary IDE channel" And "Secondary IDE channel", or "ATA Channel 0" And "ATA Channel 1" like in the picture above. We open each channel in turn and look at "Device type".

We need to find a channel with a device type "ATAPI CD drive" or something like that.

• Look at the check mark "Enable DMA". We remove it if there is one, or check it if there is no checkmark.


• Reboot the computer and look at the result.


• If it works with the option disabled, check the box again. Reboot and check.


• We leave the working option, but it is desirable that the function "Enable DMA" was turned on.

In some cases, this is the only way to get the DVD-ROM to work in Windows.

Another loophole to straighten the drive’s brains is to change the region in the settings. To do this, open your DVD drive in the device manager and on the tab "DVD Region" look at the current region.

If it is written "Current region: Not selected", then we don’t touch anything. And if some left one is selected, then we try to change it to our own. The number of attempts to change the region is only 5! If you are completely desperate, you can try to change the region from the state "Not chosen" to some other one. But you can reset it back only by flashing it.

What to do if the hardware is faulty?

First of all, I advise you to replace the cable with a known working one and change the power plug to another one. This could be the end of all repairs.

During operation, the DVD drive collects dust, which partially settles on the laser head. Due to dust, the DVD drive does not read discs, or reads them, but not all of them. It would be good to disassemble the drive and VERY CAREFUL Clean the laser eye from dust using an ear stick slightly moistened with water or purified gasoline.

But not all users can disassemble a DVD drive. In this case, special cleaning discs can help, i.e. CDs with brushes glued on. When the drive tries to recognize the disk, it spins it and the brushes brush dust off the laser head.

Due to excessively hard brushes, there have been cases of damage to the laser head. The brushes must be flexible and come complete with lubricant. So be careful with these cleaning discs!

You can also blow out the insides of the drive through the open tray using a can of compressed air, as an option.

Sometimes updating the drive firmware helps. You need to look for new firmware on the manufacturer’s website and strictly follow the instructions for installing it.

“Dying laser” is a common occurrence if a DVD drive does not read discs. Due to a jammed laser, CD discs may be poorly readable, but DVDs can be read perfectly and vice versa, since each type of disc has its own laser.

The drive has probably done its job if none of the above helped. Don’t worry and buy a new one, since today they are inexpensive.

How can you read a bad disk?

To read a bad disc there are special programs, for example paid Bad Copy or free Unstoppable Copier. Programs try to read the bad sector several times with different parameters, and if nothing works, they simply skip it and move on. In this way you can save everything you can. As a rule, for audio and video the loss is not noticeable.

Today you learned what you can do when a DVD drive does not read discs. I hope the information above will help you save money on purchasing a new drive or finding a solution to your DVD drive not recognizing discs.

That's all for now! I hope that you found something useful and interesting for yourself in this article.

What to do if a DVD-ROM does not read discs, why does this happen and how to fix the problem?

Some users ask this question when they discover that the media inserted into the drive is not detected by the operating system.

Then, before fixing the problem, you need to establish how it appeared?

Signs

The problem is nonspecific and can be detected in a very diverse manner. You can understand that a DVD-ROM does not read discs based on one general characteristic - you installed the media in the drive, but it did not appear in the system. The physical varieties of this phenomenon are as follows:

• Only media of a certain format are not readable, for example, CDs are readable, but DVDs are not. Or vice versa;
• Only media with a certain type of file cannot be read (this happens quite rarely, but it does happen);
• Only media with certain technical characteristics (capacity, recording type, etc.) are not readable;
• Only blanks (of any or a specific format) cannot be read, but media recorded in industrial conditions work properly;
• After installing it in the drive, you can hear that it is working, you can hear that the disk is spinning for a long time. But despite this, it is not determined by the system;
• Only movies cannot be played, regardless of the recording method and the presence of other files on them. Although most often we are talking about specialized movie discs purchased in a store.

<Рис. 1 Встроенный дисковод>

All types of reasons why this happens can be divided into two large groups. Hardware problems arise from the hardware side, due to its malfunction, incorrect operation, etc. Such problems are quite difficult to resolve, especially for a beginner.

Often in this case, it is necessary to replace some computer components. It’s not worth doing this, especially for a beginner who doesn’t have any special skills. It is recommended to seek the help of professionals.

The second common reason is software. That is, when the drive does not function due to the fact that it cannot communicate with the computer, due to faulty drivers, etc. Such problems can be fixed quite easily, and you can do it yourself.

Both the built-in and plug-in drive may not work. Regardless of the type of device, the methods described below can help. It is worth mentioning that for connected drives this problem is often associated with the software part, and much less often with the hardware.

Signs of a hardware problem

The device can fail for various reasons. Sometimes this is due to operational wear of heads or other hardware components, dust and other reasons. However, in these situations, it is typical to stop reading media of any type, but if only one type has stopped being read, then the problem is probably something else (with rare exceptions).

Playback side

How to diagnose a problem and roughly determine what actually happened? There are several characteristic signs:

1. If the VD opens, but the CD does not start, or vice versa, then the problem is most likely a broken laser or one that has just begun to change its functionality;
2. When inserting the media into the drive, the user hears how it makes noise, the spinning speed either increases or decreases, in some cases a grinding noise is also heard - the lens is damaged (worn out, dusty, etc.);
3. If the problem described above only occurs with one specific drive, then the drive itself is faulty and the drive is probably fine;
4. Licensed discs are detected fairly well, but unlicensed ones are not detected at all.

These are signs that may appear on the disk reading side. They are not the only ones. But these are the ones that occur most often.

From the recording side

<Рис. 2 Подключаемый привод>

A separate option is signs of a drive malfunction, detected when recording to a storage medium. From the recording side, problems manifest themselves as follows:

1. The disc is not written at all;
2. Data is written at the beginning, but then the process is interrupted;
3. The data seems to have been recorded, the system shows that the process is completed (sometimes too quickly), but such media then does not open on any other device;
4. The recording occurred or was interrupted, but the resulting disk can no longer be formatted, cleaned, or used again.

Those who often use the recording function note that if the hardware malfunctions, problems with recording appear earlier than with playback. That is, the discs stop being written to, but are still readable. This allows for timely repairs.

Troubleshooting a hardware problem

A dusty lens and a broken laser are the most common causes of such breakdowns. But often there is another reason. These are incorrectly or poorly connected cables for power supply and data transfer SATA or IDE.

This parameter needs to be checked first. To do this, open the system unit and find the wires that go from the drive to the motherboard and the computer's power supply. Make sure they are connected securely (tightly in the ports, free of dust and debris, etc.).

If the cables are connected normally, then the problem is in the drive. Fixing it is more difficult than buying a new device. It is much easier to purchase a disk drive - the price of such a component is about 1000 rubles.

In the case of laptops, you shouldn’t try to fix anything yourself. Since the drive connection system there is connected to many components. You can accidentally damage the entire device.

The solution in the case of laptops is to use a drive connected via USB. With installed drivers and correct software, such a device works properly and stably.

In principle, to repair it, it is often enough to disassemble the drive. And then wipe the lens with a cotton swab. It’s just very difficult to do this, since these devices are selected without taking into account the fact that they will be disassembled (although in principle this can be done, there are no general algorithms).

Disassembling and cleaning the optical CD/DVD drive of a PC if it is not working well

If your computer drive does not read, does not see, freezes, takes too long to read CD DVD RW discs, or simply does not work.

Software reasons

Sometimes driver malfunctions or system problems cause the device to stop working properly. This cause of the problem can be easily eliminated and does not require additional fees. Therefore, before disassembling the drive, make sure that the problem is not in the software.

Signs of a software problem

How to diagnose software problems in the system? By what criteria are they determined? Such a malfunction can be assumed if the following factors are present:

1. The device stopped functioning normally after the operating system was reinstalled or after it was updated;
2. The problems began after a manual or even automatic driver update (which happens quite rarely, but does happen);
3. Discs written specifically by a particular program, a disc of a certain format or with a certain type of data cannot be read (this can equally be a sign of a hardware or software problem);
4. Difficulties appeared immediately after installing a particular program (such problems are especially often caused by programs for working with media - Nero, Alcohol 120%, Daemon Tools).

It is quite easy to diagnose the cause of the problem in this way:

1. Turn off your computer;
2. Place the boot disk in the drive;
3. Turn on your computer;
4. Open BIOS;
5. Try booting from the disk.

Accordingly, if loading occurred normally, then the drive is working properly (at least with this type of disk). If the download does not occur, then the problem definitely lies in the hardware.

Troubleshooting

If there is a program or update that is causing the problem, uninstall that program. Moreover, this must be done through the Control Panel, and also delete all its files from the system folders. Sometimes it is also advised to “clean up” its traces in the registry, but most often this is not required.

If it is not established exactly which program caused the problem, you can roll back the system to the point at which the drive was definitely still working. Quite often this is enough, and the discs begin to be read properly.

<Рис. 4 Диспетчер устройств>

If problems arise after updating the drivers, you can do this:

1. Press Win+R on your keyboard to open the command line; Windows 10 users can simply click on the start menu and type Command Prompt manually;
2. A small command line window will open with an input field, enter the command devmgmt.msc in it;
3. The Device Manager will launch, in which you need to find the Disk Drives section;
4. Expand this section and find in the list the drive with which the problem occurred;
5. Right-click on it and in the drop-down menu click on the Delete section;
6. Now select the Action button in the menu at the top and find the Update hardware configuration item;
7. After clicking on it, the operating system will find the drive again and install the necessary driver on it.

Sometimes a partition contains some kind of virtual disk drives and partitions. It is also advisable to remove them, as they may be the cause of the problem. After this, restart your computer to resolve the issue.

Features of Windows 7

Some specific problems are observed on computers with the Windows 7 operating system. Try this:

1. Open Task Manager as described above;
2. Go to the IDE ATA/ATAPI controllers section;
3. Items like ATA Channel 0, ATA Channel 1 should open;
4. In the right block of the menu, right-click on these items and one by one go to the Properties section;
5. In this window, go to the Advanced Settings tab;
6. In the Device type field, set Enable DMA;
7. Click Apply;
8. Restart your computer.

The problem should now be resolved.

DVD drive repair

DVD player with a problem in the drive, it would not play. The repairs were made and everything worked.

There are many reasons why disk drives stop working: driver problems, conflicting applications, damaged drives. To fix a problem, first determine the source of the problem.

1. The problem is in the storage medium

If there are many scratches on the surface of the storage device, the media will not be recognized by the drive. There may also be difficulties reading discs from certain manufacturers. For example, not all disk drives will analyze L-PRO products. In this case, buy products from a different brand.

2. The disk drive does not see the disk on the laptop

When the data reader does not recognize the discs, the laser emitter is faulty. Try disassembling the device and wiping the laser head with cotton wool.

Alternatively, connect the drive to another computer. This way you can check which element of the product is not functioning properly. To process information, the drive uses different types of modes. If one of them does not work (does not receive power or power), then the disks are partially and not always recognized. For example, the drive ignores CDs, but opens and reads DVDs.

Usually the main reason for product failure is wear and malfunction of the laser head. Only replacing the device will help here.

3. The laptop drive does not see the disk. What to do?

In addition to mechanical failure, failures in the operating system may occur. If the reading device recognizes disks with information as blank, update the drivers. To do this, go to Device Manager, remove the controllers and reboot the laptop. After turning on, the PC will install the software on its own and restart.

If nothing helps, download the drivers to the flash drive from the official website of the equipment manufacturer.

Please note: virtual emulators like alcohol or daemon tools prevent normal operation of the drive. Uninstall such programs and remove the reader controllers.

4. The drive is working, but disabled in BIOS

You need to go into the BIOS and turn on the drive. The line responsible for inclusion looks like this: “CD-ROM. ENABLED" and "DVD-ROM. ENABLED".

5. Laptop drive cannot be read

If the previous steps did not help and the drive does not appear, then either it or the controller on the motherboard is broken. The product needs to be replaced with a new one.

6. No access to recorded files on the disk

This problem is a number of system ones. Since the software is responsible for launching and operating the files, the drive is functioning normally.

Update recording applications (Nero, Roxy) to the latest version on the official website of the developers or reinstall the software.

Note

If you have installed utilities that identify disk data after installation in the tray (similar to NERO StartSmart, Roxio InCD), remove applications and the drive from Device Manager.

The disk drive does not see the disk: what is the reason and what to do?

This is how it happens: you take a day off, buy an interesting movie, prepare everything you need for a romantic date, call your favorite girl. And suddenly, a wonderful evening that has not even begun will turn into a real problem - the computer’s disk drive will completely refuse to read any media. So, if the drive does not see the disk, what should you do? First of all, don't worry. There are not enough reasons for this malfunction to require a whole day of repairing your computer. Secondly, get comfortable and get ready to read this material. The article contains the most common problems that negatively affect the operation of the drive, as well as ways to solve them.

First solution to the problem

Let's start with the easiest thing - with autorun settings. They can easily go astray, but, unfortunately, they are unable to return to the original parameters on their own. If the drive does not see the disk precisely because of them, the user’s task is greatly simplified. After all, the problem can be fixed in just a few seconds: you need to go to “My Computer,” right-click on the drive shortcut and click on “Properties.” In the menu that appears, go to autorun and there, in a couple of mouse clicks, solve the problem with a non-working disk drive. After carrying out these simple steps, there is no need to restart the computer, since the new settings are applied instantly.

What else could be the reason?

The second trifle, which, however, can also prevent the drive from working stably is the drive not being enabled in the device manager. In this case, you only need to turn it on: you can do this with one click. But it is important to know where exactly the necessary button is located. In the menu of the above manager, it is located in the “use of devices” window. By the way, it is important to first see if the drive is turned on and only then change anything there. Otherwise, you can turn off a “formally” working disk drive, jeopardizing the success of all further attempts to heal the computer.
If the above manipulations did not help, there is no need to rush to exit the device manager. In its menu, you can perform another operation that may help solve the problem with the drive. It is possible that the drive is not working simply because something happened to its driver. To check this, you need to completely remove the installed driver: you can do this in the same device manager. Once it is safely removed, you will need to restart your computer. After loading again, the system will help the user download and install a new driver from the Internet. If after this the drive still does not see the disk, you will have to take more drastic action.

Let's rummage through the registry

If the drive works but does not see the disks, the problem may be in programs designed to create images, if, of course, they were once installed on the computer. Such programs sometimes leave completely unnecessary “traces” in the registry, which are easy to remove, but difficult to find. It will be much easier to return to a specific system restore point when the drive was still working and successfully performing its tasks. By the way, many users make the mistake of deleting the harmful programs themselves, and not the culprits of the problems “registered” in the registry. The CCleaner program, which is one of the most popular programs for optimizing computer performance, can help clean your system of unnecessary “garbage.” Although it won’t fix the drive, it will make the repair process as fast and comfortable as possible.

Are the cables to blame?

Have you been surfing the system a lot, are you very tired and want to relax? You will have such a chance right now, and without compromising the time needed to repair your computer. The fact is that the drive may refuse to work due to the fact that the cables connecting it to the system board have come loose. In this case, you will need to disassemble the system unit. And then disconnect and reconnect all the cables leading from the drive to the PC. If the user does not understand “all these strange pieces of hardware” well, he does not need to disassemble anything at all - it is better to involve people who can find the necessary cables and carry out the necessary actions correctly. The same advice should be given to happy owners of laptops - there is no need to try to fix something where nothing is clear! You can make sure that the problem is in the detached contact in the BIOS: if the drive is not displayed there, then you may be very close to solving the problem. By the way, it’s also not worth wandering through the BIOS menu without understanding anything there - you can lose the system.

User, help yourself!

When wondering why the drive does not see the disk, people often completely forget that the problem may be in the system itself. If this is the case, you will need to install various antiviruses one by one and scan the system for vulnerabilities. By the way, not only specialized programs for searching for viruses can help. The Advanced System Care program successfully searches for system vulnerabilities and instantly eliminates them, which can also optimize the system in the meantime.

Cleaning the drive: why is it needed?

Have you tried all the ways to solve the problem, but the drive still doesn’t see the disk? Perhaps it was just very dusty. It is not recommended to disassemble and clean it yourself. It is better to buy a special cleaning disk, which, thanks to the presence of special cleaning brushes, can do its job very efficiently. When purchasing it, it is important to pay attention to the softness of the cleaning devices - too hard, inflexible brushes can scratch the drive laser.

One problem and one solution!

If the CD drive does not see the disc, it is possible that it simply does not support it. In order for absolutely all discs to be played on your computer, you need to buy a multi-drive. Nothing helps to eliminate the problem that the drive does not see the disk, despite numerous attempts to “cure” it? Then just make sure that this is the problem and go to the store for a new drive. Nowadays, thanks to rapidly developing technologies, you can buy a high-speed, high-tech drive: it will delight its owner not only because it works, but also with high recording speed.

The laptop does not read discs: instructions for solving the problem

To understand the reasons why the laptop does not read disks, it is necessary to analyze the situation - how exactly did the malfunction occur? What events preceded the problem?

If the computer has been in use for a long time, it is logical to assume that the power of the laser beam has decreased significantly over time. In this case, the drive usually first stops writing information to discs, and after a few months it becomes impossible to play back.

Some types of disk drives have an option to increase laser power. For this purpose, there is a special adjustment screw on the body. The problem is that laser amplification will force the equipment to work in a forced mode and this will soon lead to the final destruction of the laser source.

If the discs are not only unreadable, but the tray does not open at all, it can be assumed that there is no power to the device. There could be several reasons for this.

• The contact in the connecting wires is broken. You need to turn off the computer, perform an external inspection, disconnect and reconnect the power and data cables.
• Malfunction of the motherboard or south bridge.
• The tracks on laptop boards are very thin and often burn out. A short circuit most often occurs after liquid gets on the laptop keyboard. Burnt tracks and contacts can be detected by visual inspection. Some advanced users even repair gaps in tracks on the motherboard themselves.
• If the laptop has not been recharged for a long time, the battery may not have enough power to operate some of the computer's power-consuming devices properly. To check this version you just need to connect the charger to your laptop and wait a while.

The disk drive could break, and not only at the laser level. The test is usually carried out by installing a known-good analogue or installing the problematic unit in another computer.

Software problems

Sometimes a situation where the laptop does not read discs is caused by the operation of certain applications, such as Nero. If any virtual disks were previously created on the computer, the system could switch to them, and the physical drive would seem to disappear from the general list of connected equipment.

To find out if the drive is connected, you need to open Control Panel and view the list of connected devices. If the problem is with your disk management software, the physical drive may not be listed in the hardware list, but virtual disks will be shown.

To begin with, you can try simply removing the virtual disks and turning on the physical drive. Perhaps after a reboot, reading DVDs and CDs will be restored.

The next probable reason is that the device drivers are not working correctly. How can you reinstall the drivers if the drive does not read and it is impossible to use the set of files from the Windows installation distribution? All that remains is to look for the necessary drivers on the Internet. The best way is to go to the official website of the manufacturer of the type of drive that is installed on your computer.

If you are not sure which drivers are required, you can go another, simpler route. Download and install a special program from the Internet that automatically analyzes the computer system and checks the availability and relevance of drivers.

The utility itself will check the availability and functionality of drivers and then automatically find and install them. As an option, you can run the Windows OS automatic update system; in the overall process, the latest drivers for the optical drive will be installed.

Problem with BIOS settings

For some reason, the laser drive was disabled at the basic BIOS settings level. Go to CMOS settings and check. If it says that the drive is unavailable, you just need to re-enable it by selecting Enable instead of Disable from the drop-down menu. Then restart Windows. Even easier is to reset the BIOS settings to default. If you did not do anything special with the BIOS settings, such an operation will not harm the performance of your computer.

The computer is infected with viruses

If you are an active Internet user, like to visit little-known sites, often install new programs, follow links in emails, the likelihood that your computer will receive a portion of malicious viruses is very high.

First you need to check the system. Enable antivirus scanning. After removing infections, the antivirus usually prompts you to restart the operating system for a final repair.

If after an overload the disks are still not readable, it could very well turn out that your digital horse got a really serious illness that severely destroyed the operating system. Viruses often destroy important system files and disguise themselves as their names.

In this case, you cannot do without formatting the hard drive and a new installation of OS Windows. In less dire cases, it may be enough to simply roll back Windows to one of its previous states. Go to the System Restore interface and find the checkpoint when, as you remember, the laptop still played laser discs.

Some models of laptops and netbooks have a system rollback function to factory settings. In this case, you don’t even need to use a Windows boot disk, which is simply unreadable.

The drive does not read discs.

What to do if DVD ROM does not read discs? The computer freezes when a disc is inserted, or when copying a movie or music, an error appears. So what is the matter - a scratched disk or the disk drive is to blame. Let's look at the causes and methods of eliminating these computer malfunctions.

Determining the reason why the drive does not read discs

If previously the disks were read normally, but after the next reboot the computer cannot read more than one disk, then most likely the reason is in the software or, more simply, some installed program conflicts with the DVD drive.

If the computer does not read only some discs, then the problem is in the drive itself, but we will try to fix even this problem ourselves; we will discuss this below. First, let's see if it's possible that the problem lies in the operating system.

For reference, the problem may be not only with reading disks, but also with writing them. The instructions below may be equally effective in resolving both problems.

Software conflict

In the event of a software error, the drive stops reading discs immediately, rather than gradually getting worse and worse. This may be preceded by an installed program or toy. Programs for creating virtual drives often conflict with drivers installed on the computer for DVD-ROM drives. The most popular of these programs are Alcohol 120%, Daemon Tools and Nero. We simply remove these programs and undo the changes they made through System Restore. Go to Control Panel => Action Center => System Restore and select the date to which you should restore. Select a date when the drive was still working without problems.

We look at the result; if the problems have disappeared, then the remote program is to blame; if not, we move on.

Driver error

The drive may not see the disks due to errors in the driver. By pressing the key combination “Win ​​+ Pause”, open the device manager from the menu on the left.

In the list of devices, we delete virtual drives, if this did not happen after uninstalling the programs that we met above. Right-click on the virtual drive and select “delete” from the drop-down menu. To completely remove the traces left behind, we need to find the “SPTD” driver and remove it. To make it appear, turn on the “Show hidden devices” option in the “View” menu. You will be able to view the changes after restarting your computer.

If the problem does not disappear after rebooting, proceed to the next step. In the task manager, go to “IDE ATA/ATAPI controllers”, and among the devices called “ATA Chanel” we need to find the one that is responsible for the CD-ROM. To do this, you need to open the controller properties and go to the “Advanced parameters” tab.

The "Device Type" line should be "ATAPI CD Drive". See if the “Enable DMA” checkbox is checked here, try to start the system both with the function enabled and with it disabled. This method often helps to get the drive to read discs in Windows 7.

If the drive does not read only video DVD discs, then perhaps the wrong region is selected in the drive settings. In order to change regional settings, go to the task manager and open the properties of the DVD-ROM. Go to the “DVD Region” tab and select your region, but if the “Current Region” line is set to “Not Selected,” then it’s better not to change anything.

CD drive problem

All DIY drive repairs come down to replacing the IDE or SATA cable from the drive to the motherboard. You can also try connecting a different power connector; usually the power supply has a couple of free connectors. And the last thing that remains for us is to clean the disk drive laser.

To clean the laser head, remove the drive cover and very gently wipe the laser with a cotton swab.

Do not use acetone, alcohol or other aggressive liquids. Instead of the expected result, you will lose the drive forever. The best choice would be water or, as a last resort, high-quality gasoline for lighters.

If you don't want to risk disassembling the drive, you can purchase a special cleaning CD that will also effectively clean the laser eye of accumulated dust.

The laptop does not see the DVD drive: instructions for solving the problem

Unpleasant situations in which the laptop does not see the DVD drive happen to owners of personal computers quite often. What is the problem here and is it possible to resolve the issue yourself without contacting a service center?

Unlike a desktop computer, a laptop is a candy bar, a single device that cannot simply be disassembled into separate modules and checked for serviceability of components by replacing them with known good ones. Therefore, the average user can do little in terms of laptop repair.

The main reasons for DVD drive failure in laptops

• Violations in the operating system and software settings.
• Connection problems - connecting cables, controllers, contact groups.
• The DVD drive itself is faulty.

When it comes to optical devices whose functional elements are lasers, a common reason for equipment failure is the simple accumulation of dust in the housings. Dust interferes with the passage of light rays and at the same time creates electrostatic fields that affect electronics. Dust is highly conductive and can create unwanted electrical connections that can greatly affect the operation of equipment.

It is strongly not recommended to clean your laptop from dust on your own. This work requires certain qualifications and special tools. It’s better not to meddle with a household vacuum cleaner in your laptop. Prudent users have their laptops cleaned at least once a year.

A common reason that a laptop does not see the DVD drive is special programs for working with discs - Nero, Alcohol 120% and similar powerful packages. These programs are deeply embedded in the system and registry of the computer, making their own reconfigurations and switches there. Sometimes, while working with such programs, the computer gets confused and begins to recognize the newly created virtual disks, but stops seeing the physical DVD drive.

If you have a similar situation, try uninstalling the disk program and see what happens. After removal, check to see if there are any virtual disks left on the laptop’s hard drive. These also need to be removed.

A simpler and no less effective way to get rid of the harmful effects of 120 percent Alcohol or Nero is to roll back the Windows operating system to an earlier state. Select a return point when these suspicious applications have not yet been installed. For the future, before installing any new program, be sure to create a revert point, just to be on the safe side.

An even more effective way to remove all unwanted computer settings is to format the laptop hard drive and reinstall the Windows operating system. As practice shows, after such a radical update, most problems disappear and the computer will start working like new, stops slowing down, and functions that the user has already lost the habit of are restored.

Problems connecting the drive

If the laptop was disassembled and components were switched or replaced inside, or the DVD drive itself was replaced, there is a high probability that violations occurred with the connection of the drive.

1. The connections in the contact groups are broken.
2. Cables or cables are damaged, contacts are broken or bent.
3. Power is not connected to the drive.
4. The controllers on the motherboard are faulty.

If the controllers malfunction, most often there will be parallel problems with the keyboard and touchpad. In this case, it is necessary to replace the south or north bridge on the motherboard (one or the other, depending on the drive model). The operation cannot be performed at home. Only to the service center.

If your DVD drive has been in use for quite a long time and is used intensively, it is quite possible that the laser will become exhausted. Usually, the drive stops writing files first. Then you can read data from DVDs for several months. And, as a sad result, it is impossible to even play recordings from discs. If this is what happened, it is definitely necessary to change the DVD drive to a new one.

Sometimes, due to inaccurate switching, individual contacts in the drive connections to the power supply or other components of the laptop are broken. Externally, this can only be detected after disconnecting and using a magnifying glass or magnifying glass.

It happens that the fixing screw is tightened too much and this leads to deformation of the connectors. As a result, everything looks normal, but there is no contact and the device does not work. All these violations in the connections cannot always be detected during a visual inspection. Often, switching problems can be found and corrected only with the use of special devices and tools.

Check to see if the laptop's DVD drive shows up in Windows Explorer. Sometimes the drive is simply disabled for some reason or accidentally as a piece of hardware. Log into the control panel, open Hardware Installation and see whether the DVD drive is enabled or not. If the system detects a drive, but it is designated as “off,” you need to change the checkbox to “on.” You can also remove the device driver. After rebooting the computer, the driver will be reinstalled and everything should work.

What is WhatsApp and how to use it on a computer

Good day.

Owners of computers or laptops may encounter a situation where the drive does not see Windows 7 disks. However, 15 minutes ago everything was fine. What happened? In fact, as always, there can be many reasons. Most often, troubles are associated with the operation of some software. In addition, this is affected by a driver failure. And sometimes this happens as a result of failure of the drive itself. In this article I will tell you how to bring your device back to life.

The first thing that needs to be done is to establish the cause of the disease. So, first, let’s examine the portable memory itself. If there are no scratches or damage to the metal coating on the disk, proceed to checking the disk drive.

To do this you need to use various CDs and DVDs. It is best if they are licensed. If there are none, you need to use only recently recorded ones. Are you sure the problem is not in the portable memory? Let's move on.

It is necessary to check whether there is a response signal from the component. You need a little:

Think about what you've been doing on the computer lately. Perhaps some new software was installed on the equipment. Or vice versa - it was deleted. What to do in the latter case? The solution is to reinstall the driver. In the first step, you need to find new software and remove it.

By the way, you can find suitable software for your device on the website of the equipment manufacturer or motherboard developer. In addition, there is an option to use one of the programs that allows you to find the necessary software and install it.

In addition to all of the above, ordinary dust and hair from pets can cause problems with reading the drive. How to clean it from this? Open it and look inside using a flashlight. If he refuses to do this, we will use a paper clip and a special small hole on the front wall. And then, using cotton swabs and other soft tools, we clean it. You can see it in detail in the video:

Microsoft Fix it( )

If suddenly the above did not help, and discs are still not readable on your laptop or computer, you need to use special software. One of the most successful solutions is considered Microsoft Fix it. You can find the official software directly at developer website. The main thing is to choose the appropriate bit depth - 32 or 64 bits. In addition, it is better to pay attention to the assembly - maximum or home. Next we go through a series of steps:

We launch the installer, read the license agreement, and accept everything.





The application will launch a system scanner. We wait until the solution finishes working with the drive.

Then we select the appropriate help option.



A window will appear asking you to place the disc in the drive. The device will open on its own. We install portable memory (again, it’s better to use licensed or only recorded memory). Click " Further».
