If the drive can read other disks, it can t read the system disk, but it can read this system disk o

What do you mean by reading?

Is it reading data in the system, or is it booting from an optical drive?

The optical drive can read other disks, which means that your optical drive is fine, and the problem is on the disk.

First of all, you have to know what kind of optical drive your optical drive is, there is a CD optical drive, *** optical drive, the optical drive is different, and the disc that can be read is also different, if your optical drive is a little old, then the general reason is the optical disc.

The CD drive can only read the CD disk, not the ***-r, ***+r disk.

The optical drive is different, you can read CD disks and *** disks.

In addition, if you want to install the system, set up the optical drive to start, but can't achieve it, the reason is the installation method of the system disk, some machines, you must use ghost to install the system, and some must use the installation version, and the general notebook needs to install the version.

Hehe, I've had this problem on my computer, try it. It's not a system problem, it's not a hard drive problem, it's a motherboard problem. This is my personal opinion, unplugging the motherboard battery.

Let the machine be powered off for a week, and it will return to normal. I don't know how long I've been broken.

I remember thinking it was a cable issue, but it was good on other machines. There's no way to power off the motherboard. I ignored him.

After a while, it will be fine. Now I continue to use it. I don't know when he won't read again. Anyway, if you have money, go to the doctor and do a good job. Don't toss around at home. It's tiring and a waste of time.

I don't know what model your computer is, now I give you a few common types of computer solutions for this type of failure!

Case 1:

ACER 350TE can not find the disc drive letter when entering the system after booting, disassemble the disc drive and put it on another machine, the disc drive can be used normally, suspect that the optical drive interface is damaged, solder the interface and clean it with alcohol, troubleshooting. This type of failure often occurs on models where optical drives are hot-swappable.

Case 2:

After Sony 505LE is turned on, there is a disc letter but the disc is not read after being put into the disc, and the disc rotation sound can be heard. After inserting the disc, the reading indicator light keeps flashing, and the sound of the laser head tracing up and down can also be heard. Eject the optical drive and forcibly move the laser head assembly outward, then close the optical drive.

Wait until the indicator light does not flash and then pop out the optical drive, at this time, we see that the laser head assembly has not moved or reset, according to this fault phenomenon, it is suspected that the tracking motor of the optical drive is damaged. Troubleshooting after replacement.

Case 3:

The Compaq EVO N1000V device has normal attributes, but it does not read the disc when it is put in, and the disc reading sound cannot be heard. When the optical drive is removed, it is found that the data connection cable between the internal circuit board of the optical drive and the laser head assembly is detached. After reinstalling, troubleshooting.

Applause Case 4:

Compaq EVO N800V is put into the CD, the start of the disk reading is normal, after half an hour, the reading indicator flashes but there is no progress display, at this time, the data on the disc can be read, but due to the poor thermal stability of the data processing chip, it cannot be transmitted to the computer. Replace the data processing chip or logic circuit board, and the fault can be eliminated.

Case 5:

IBM A21M optical drive can sometimes read and sometimes can not read, remove the optical drive and put it into another machine for detection, the optical drive reading disk is completely normal. It is suspected that there is a problem with the IDE interface of the host, and it is found that there are two pins at the interface and the motherboard soldering.

Case 6:

The Sony 505GL does not have an optical drive letter after entering the system, and the optical drive hardware device cannot be found in the system properties. The optical drive of this type of model is on the base, and the base can be separated from the body. This type of base does not support hot swapping, if it is directly hot-swapped, it will cause damage to the main control chip in the base, and the machine cannot find the optical drive.

If the same model chip can be replaced or the internal program can be re-flashed, the troubleshooting can be done, otherwise the entire base must be replaced.

Case 7:

The toshiba 2400 optical drive hardware device driver loads normally, but it does not read the disk. Nothing happened when I put it into the disc. Disassemble the optical drive for inspection, and it is found that the laser head can be reset normally.

The disc that was put in did not respond at all. The spindle motor was disassembled and powered on, and the spindle motor was found to be damaged, and the fault was troubled after replacement.

You're talking about a CD-ROM drive.,You can try to rinse the disc with clean water first.,Then wipe it dry.,Put it in the CD-ROM and try again.,If the disc is scratched, it can be solved.,But if all the disks don't read.,Then there's a problem with your CD-ROM drive.,Go buy a new one.,The ordinary *** CD-ROM drive is about 120RMB,Burn about 160-180,It's cheap。

The optical drive can be removed.

Rub the laser head with an alcohol cotton ball.

It should be ok. If your optical drive is very old.

There is no value.

It is recommended to replace it.

Generally speaking, if the optical drive is broken, there is no value in repairing. Because the computer's optical drive is broken, it is generally a broken bald head. If the computer optical drive is broken, it is not a household ***, and the damage to the household *** may be its motor damage or the bald head has a gray spring stuck.

Try to change a few more discs, if you can't read them, you can only change the optical drive.

Check whether the data cable and power cable of the optical drive are properly connected.

If the computer drive has been used for n years for a long time, the read and write performance will be degraded!

1. First of all, take a look at the status of the optical drive properties in the device manager: if it is disabled, you can enable it.

2. Check the flatness of the platter, if there is no warping, check the optical drive.

3. Check the optical drive: do not read the CD disk, or selectively read, and exclude it according to the following conditions

Device Manager - cd *** drive properties - *** region (the current region should default to vacancy, if there are other regions, then change to China), there is a locale setting can only read the *** disc of this region.

If the area is vacant by default, it can be determined that the head is RF aging, and you can guarantee it or find a professional to increase the head frequency.

In addition: notebook optical drive consumables, it is recommended not to use or use less of the burning function of the optical drive, which will accelerate the aging and damage of the magnetic head.

When burning, try to use low-speed burning, 4x is the best.

However, there will be a problem of head aging when the optical drive is burned, and in serious cases, it can only be read and cannot be burned, that is to say, the radio frequency of the head is not enough to cause the power supply to be unstable and fail when the optical drive is burned.

The optical drive is like this, and there will be problems if you don't use it for a long time, and there may be two kinds of questions about yours:

One is because of the problem of the laser head, because it has not been used for a long time, there is ash on the head;

The other is mechanical failure.

What is the specific situation, it depends on whether you put the disc in, whether the optical drive will have abnormal noise when reading the disc or the optical drive will continue to accelerate. If there is an abnormal noise, it is possible that the optical drive can only have mechanical sock rental barriers, which may be caused by vibration and internal component problems, or it may be caused by foreign objects entering the optical drive, because the internal components of the optical drive are relatively fine; If it is constantly accelerating when reading the disk, it may be that the laser head cannot read the data, and it will accelerate one gear to increase the speed, and then accelerate again if it cannot be read.

The above is what I have in mind, whether it is or not, it depends on the actual situation.

I don't know what the specific problem is, I guess it's a broken disk, you can format it, sometimes you change the system, this problem will also occur, especially window7, I've had this situation.

There are several reasons for this:

1. It is common to delete the shared text of the optical drive by mistake when installing software (such as Lianliankan, virtual optical drive, etc.), resulting in the optical drive being unable to recognize. Try it after reinstalling the system.

2. The optical drive data cable on the motherboard is not connected firmly, or the interface is problematic;

3. The optical drive laser head is aging and cannot be read, if the reinstallation system still cannot be solved, it is recommended to do hardware detection.

4. Very few causes are caused by viruses. Author: Coodoo Sun |Level 4 | 2011-1-21 03:42 |Report.

In this case, it can only be considered that the optical drive is broken, you can find an optical drive from elsewhere to try, if it can be used normally, it means that it is not the problem of your machine itself, but the problem of the optical drive itself or the optical drive cable!

It is recommended to use the elimination method, first exclude the optical drive cable, and then exclude the motherboard interface, and the rest is that the optical drive itself is damaged!

It may not be able to be read as follows.

1. You may be a CD drive, and to read *** CD, the CD drive can only read CD discs. Read *** disc requires *** optical drive.

Second, it is possible that the optical drive is aging, now the laser head of most of the optical drive is not as good as before, and the optical drive is often used like the laser head aging too fast, you say that the movie disc and CD disk are generally non-burning discs (you look at the color of the disc surface, silver white).

Nowadays, many drive disks are made of burning disks (disc color, CD disks with a little yellow-green, *** disks with blue), this kind of burning disks, if the optical drive is a little old, the reading effect will be poor, not as stable as non-burning disks.

This is normal,In fact, the optical drive is also compatible,Your other disks can be read to indicate that your optical drive is fine,Other unreadable means that those disks are not compatible with your optical drive,So it can't be read。 This kind of problem is very common.

The optical drive is divided into *** and CD's image is compatible not up, if it is a CD optical drive, it will not be able to read *** disc.
