After putting the disc in, the light is flashing, but what happens if the disc is not read?

It may be that the disc is broken or stolen, take the disc out and wipe it with a soft object, and try again.

Check whether the optical drive cable is normal first! Check if the optical drive is good! Finally, check if the disc can be read on other computers! Or whether the disc is good or bad!

If you are sure that it is not the problem with the disk, you can try cleaning the optical drive head or turning the optical drive head out to read the disk again

If you can rule out the quality problem of the disc, your optical drive head is dirty after long-term use, you can clean it.

Try to change the disc, if it doesn't work, the optical drive is broken!

The possibility of the bald head not reading the disk is very high, you can see if the disk that is put in is rotated, that is, remember the direction of the disk pattern when you put it in, and you will be out of the warehouse to see if the direction has changed, if it changes, it means that it can not read the disc with the bald head, if it does not turn, it is the other components of the optical drive.

This phenomenon seems to be relatively common, do not blindly replace the optical drive, the following reasons are for reference:

1: Operating system problem, a certain program file is corrupted. - Reworked the system.

2: Infected with Trojans or software conflicts. - Anti-virus or check for a newly installed software program, and uninstall it if necessary.

3: The optical drive comes with a manual ejection key, leakage or sticking. - Disassemble and scrub.

4: If the above operation is invalid, change the optical drive.

Some discs are unreadable: this is the case of "disc selection". It is impossible for a device (such as an optical drive, recorder, machine, CD player, etc.) to read any disc, and it is impossible for a disc to be read on any device.

On the one hand, due to the different degrees of newness, manufacturers, quality, performance parameters and frequency of use of the equipment, the reading ability of each equipment is different, that is, the "error correction ability" is often different. The same disc, read on different ** devices, will have different results: some can be read, some are difficult to read; Some can't be read.

** equipment that is difficult to read and cannot be read belongs to the phenomenon of "disk selection". On the other hand, the quality of each disc is not the same, and the results read on different ** devices are also different. The same disc can be read normally on a device with strong error correction ability, but it will be difficult or impossible to read on a device with poor error correction ability.

When encountering a choice, it is necessary to find the reason from two aspects. 1. Broadcasting and late defense equipment: Most of the problems are as follows:

The device does not support the format of the disc, the bald head is not clean or damaged, the laser power is reduced or defocused, the performance is degraded, the error correction ability is poor, the decoder board is faulty, the data cable or power cable is disconnected or the contact is poor, etc. Any problem may cause you not to read the Dankai disc or choose the disc. 2. CD-ROMs.

For example, disc quality problems (including the quality of the blank disc and the quality of burning, as well as the high burning speed, the disc surface is stained with dust, dirt, damage, etc.), disc deformation, scratches, dirt, disc format, regional restrictions, etc.

Solution: Before confirming that there is no problem with the disc, you can first clean the bald head with a cleaning disc to rule out the cause of the dirty bald head. If it doesn't work, it may be that the bald head is aged or broken.

This should be divided into two parts, one is the CD, and the other is the CD-ROM drive.

If the quality of the data reflective surface on the disc is not good, it can cause difficulty in reading the data, forming the fault phenomenon you described, and the solution is to try it on a *** disc.

If you have dust inside the optical drive, aging of the laser head, poor contact of the data cable (experience shows that this possibility is relatively small), and the poor operation of the laser head trolley, etc., can cause the fault you described.

You can solve these problems yourself.

For dust, you can open the case of the optical drive, wipe the laser head with suede and make a circle from the inside to the outside (preferably with an ear blowing ball) to clean it.

For the aging of the laser head, in addition to replacing, you can extend its service life by increasing the current of the laser head, this adjustable resistance is on the laser head trolley, you can try to adjust it, be careful not to adjust it too much, if there is no effect, it must be reset.

For cable problems, you can just reseat it and try it again.

If the laser trolley does not move, you can gently move it with your hand to help it move to see if it can read the data, if it can be read, you can use some white butter to rub some on its track until it can move smoothly.

This situation generally occurs in the following situations:

1. If the computer optical drive driver is damaged or conflicts with the system, it is recommended to uninstall the optical drive and reinstall the driver to give it a try.

2. If the internal files of the optical drive are damaged or missing, it is recommended to rewrite the following optical drive files;

3. If none of the above can be solved, it is generally the optical drive that has been damaged, or a new one, and the current optical drive is also very cheap.

Find a screwdriver yourself, take it apart, it's not expensive anyway, use a piece of absorbent cotton to gently wipe your head to ensure that you don't have a problem using it for another half a year. Remember, move lightly and not forcefully.

The hard drive should be poisoned, if there is nothing important, format it.
