Common fault repair technique for optical drive

You should know that "optical drive" is one of the most useful parts in computer hardware. This article is mainly for the CD-ROM common fault maintenance skills Daquan for everyone to explain, I hope you like!

In fact, a lot of scrap optical drive still has a lot of use value, as long as a little repair can be. This often does not require any advanced radio expertise, nor does it require the use of too complex maintenance tools and materials. As long as you carefully observe the fault phenomenon and follow the implementation of some of the following exclusions, I believe your avoid drive can still restore the former "style".

Computer Failure Repair Daquan: optical drive common fault repair skills

Common failure One: hard drive light always flashes when the CD drive is working

This is an illusion, which is not actually the case. The hard drive light flashes because the optical drive is connected to the hard disk on an IDE interface and the disc is working with the result of the hard drive light. The optical drive unit can be connected to an IDE interface alone.

Common Failure II: Display "32 disk access failed" When operating on a CD-ROM in a Windows environment, and then crash

Obviously, Windows 32-bit disk access has a certain impact on the CD-ROM. Most of the CD-ROM is connected to the IDE interface of the hard disk, and Windows 32-bit disk access is not supported, causing Windows to crash with an internal error. When you enter Windows, double-click Control Panel in the main group, go to the 386 enhanced mode setting, click the Virtual Memory button and then click Change, turn off the 32-bit disk access check box in the lower-left corner, and then restart Windows after you confirm. There is no error in accessing the CD-ROM in Windows.

Common failure Three: the optical drive does not read the disk normally,

The screen shows: "There is no disk on drive X, insert disk retry," or "Cdr101:not ready READING drives x ABORT." RETRY. FALL? " Occasionally in and out of the box are also read the disk, but soon do not read the disk.

In this case, the virus should be detected first, with anti-virus software to carry out the whole machine to kill poison, if not found viruses available file editing software to open the C-packing directory Config.sys "file, to see if it is also hanging on the driver and driver is destroyed, and processing, and can also be used to view text editing software "Auioexec. BAT "file with" MSCDEX. Exe/d:mscdooo/m:20/v ". If no problem is found in the above two steps, the optical drive repair can be removed.

Common trouble Four: read-write error or no disk prompt when light is driving

This phenomenon is mostly caused by the failure to operate the optical drive while the disc is being swapped. All operation of the optical drive must be done when the optical light is displayed as a good bit. You should also adjust the time to 0 o'clock and then change the disc when playing the DVD, so that you can avoid the above error.

Common Failure V: when playing movie VCD, there is a pause or a broken phenomenon

Check to see if "Smartdrv" in the Autoexec.bat file is placed after MSCDEX.EXE. If, the SMARTDRV statement should be placed before the MSCDEX.EXE, the high-speed party-to-party smartdrv.exe/u without using the optical drive, the fault can be eliminated.

Common Failure VI: optical drive when reading data, sometimes can not read, and read the disk time to become longer

Optical drive Read disk hardware failure is mainly concentrated on the laser head assembly, and can be divided into two cases: one is the use of too long to cause the aging of the laser tube, the other is that the surface of the photoelectric tube is too dirty or the laser tube lens is too dirty and displacement deformation. Therefore, when the laser tube power is adjusted, it is necessary to clean the optical tube and laser tube lens.

The cleaning method of the photoelectric tube and the focusing lens is: Unplug a set of flat cables connecting the laser head assembly, remember the direction, and disassemble the laser head assembly. At this point, you can see the cover of the laser head focusing lens, remove the sheath will find the focus lens from four thin copper wire connected to the focus, tracing coil, the photoelectric tube assembly is installed in the small hole just below the lens. Wipe with a small amount of distilled water with a thin wire wrapped in cotton (no alcohol can be used to wipe the photoelectric tube and the focusing lens surface), and see if the lens is horizontally dangling from the laser tube, otherwise it should be properly adjusted. At this point, the cleaning work is complete.

Adjusts the power of the laser head. On the side of the laser head assembly there are 1 small potentiometers like a Phillips screw. Use the color note under its initial position, generally first clockwise rotation 5°~10°, installed test machine no longer counterclockwise rotation 5°~10°, until it can read the disk smoothly. Attention must not be rotated too much, lest the power is too large to burn the photoelectric tube.

Common fault Seven: The boot detection is not optical drive or detection failure

This may be due to the optical drive data cable connector loose, hard disk data cable damage or optical drive jumper settings error caused, when encountering this problem, we should first check the optical drive cable connector is loose, if found not plugged in, it is plugged in, and inserted tight. If this still does not solve the problem, then we can find a new data cable to try. At this time if the fault persists, we need to check the disc's jumper settings, if there is an error, change it!
