Seven, optical drive
The optical drive is one of the latest accessories in the computer hardware. In fact, many scrapped optical drives still have a lot of value, as long as it is slightly repaired. This often doesn't need to have any high-profile professional knowledge, nor does it need to use what too complicated repair tools and materials. As long as you look at the fault phenomenon and refer to some of the following troubleshooting methods, I believe your old drive is still recovering "style."
Common faults 1: The hard drive light is always flashing when the optical drive is working.
This is an illusion, it is actually not the case. The hard disk light flashes because the optical drive is connected to the hard disk on an IDE interface, and the optical disk also controls the result of the hard disk light. The optical drive unit can be aligned on an IDE interface.
Common Fault 2: Display "32 Disk Access Failure" when operating the CD-ROM in a Windows environment, then crash
Obviously, Windows's 32-bit disk access has a certain impact on CD-ROM. Most of the CD-ROM connects to the IDE interface of the hard disk, does not support Windows 32-bit disk access, so that Windows produces internal errors and crashes. After entering Windows, double-click the Control Panel in the "Main Group", go to the "386 Enhancement Mode" setting, click the "Virtual Memory" button, click "Change", put the "32-bit Disk Access" in the lower left corner " The verification frame is closed. After confirming, restart Windows, and then access the CD-ROM in Windows will not errors.
Common fault three: CD-ROM does not read the plate normally
On the screen: "There is no disk on the drive X, insert the disk again", or "CDR101: NOTY READING DRIVE X Abort .Retry.fall?" Occasionally, the box is also read several times, but soon not read the disc.
In this case, the virus should be detected first, and use anti-virus software to check the anti-virus, if the virus can be found, the virus can be found in the CONFIG.SYS file under the C-plate root directory, see if it is mounting Whether the program and the driver are damaged, processed, and the text editing software is also available in "AuioExec.BAT" files in "Mscdex.exe / D: MSCDOOOO / M: 20 / V". If the above two steps have not been found , Detachable optical drive repair.
Common faults 4: Read and write errors when using the optical drive
Most of this phenomenon is the failure of the CD-ROM drive when there is no in place when the disc is changed. Both all operations of the optical drive must require the disc indicator to display as a good position. When playing a movie, the time should also be transferred to zero, so that the above errors can be avoided.
Common faults 5: A screen pause or crushing in the playback movie VCD
Check if "smartdrv" in the autoexec.bat file is placed behind Mscdex.exe. If so, the SmartDRV statement should be placed before Mscdex.exe; the high-speed party group of the CD-ROM drive is not used to change to smartdrv.exe / u; the fault can be excluded.
Common fault six: When the optical drive is reading data, sometimes it can't be read, and the time of the reading disk becomes long.
The hardware failure of the optical drive read pan is mainly concentrated on the laser header assembly, and can be divided into two cases: one is to use too long to cause laser tube aging; the other is that the surface of the photoelectric tube is too dirty or the laser lens is too dirty. And displacement deformation. Therefore, when the laser tube power is adjusted, the photoelectric tube and the laser lens are also required to be cleaned.
The cleaning method of the photoelectric tube and the focus lens is to unplug a set of flat cables that connect the laser head assembly, remember the direction, unplug the laser head assembly. At this time, you can see the laser head focus lens. After the sheath will be removed, the focus lens will be found by four fine copper wires to the focus, the trail coil, the photoelectric pipe assembly is mounted in the small hole below the lens. Wipe with a small amount of distilled water with a fine iron wire (not available alcohol to wipe the photoelectron and the focus lens surface), and look at whether the lens is horizontal and positive to the laser tube, otherwise it must be appropriately adjusted. At this point, the cleaning work is completed. Adjust the laser header power. There is a small potentiometer like a cross screw on the side of the laser head assembly. Using color notes, its initial position is usually rotated first, 10 ° ~ 10 °, and the installed test is not rotated in counter-hour, until it can be smoothly read. Note that there is too much to rotate, so that the power is too large and the photoelectric tube is burned.
Common fault seven: boot detection of optical drive or failure
This is possible because the optical drive data cable is loose, the hard disk data line is damaged or the optical drive jumper setting error is caused. When we encounter this problem, we should first check if the optical drive's data cable connector is loose, if it is not shown, Just reinsert it, insert it. If this still can't resolve the fault, then we can find a new data cable for a try. At this time, if the fault still exists, we need to check the jumper setting of the disc, if there is an error, change it.
