Some users use the computer to find that the optical drive icon is missing, and the optical drive icon cannot be found in the system attribute. This is usually because the driver of the optical drive or recorder fails.So what should I do if the optical drive is gone?Lets take a look at it together.
Reasons why the optical drive is not seen: hardware aspect
1. The IDE driver installation error or conflict with a driver
If we install the IDE driver correctly in installing Windows, or when you open the device manager to find the hard disk controller after the installation, you find that there is a yellow exclamation mark in it, the disk of the optical drive may not be found.
Under normal circumstances, when we enter a safe form, the disk of the optical drive will not be available.If we want to use the optical drive in a security form, we can load the driver of the optical drive in AutoExec.bat and Config.sys files, so that we can use the optical drive under security after restarting the computer.
If we are infig.The number of LastDrive =? Is set in the SYS file. The number of drivers is smaller than the actual driver. At this time, even if we install the optical drive, the shadow of the optical drive cannot be seen on my computer.At this time, just remove the settings or set to LastDrive = Z.
3. Improper DMA settings
If the optical drive only supports the PIO4 standard and does not support the DMA/33 standard, we forcibly let the optical drive use the standard (to set the DMA in front of the option in the device manager in the device manager in my computer attribute).At this time, the optical drive is lost, and sometimes the computer cannot start normally.
At this time, we can enter the security form and remove the DMA settings in the CDROM attribute.What kind of data we use to use the hard disk or optical drive we use can support the form of infusion, we can see in the fundamental configuration table of the second screen during the computer startup process.
4. The optical drive is maliciously blocked in the registry
It should be noted that some viruses are now specifically changed the registry to lose the light drive symbol.Some viruses do not lose the light drive letter, but the optical drive reads the disk. What kind of discs cannot be read, but they can start with a CD.
5. Is the driver of the optical drive be installed correctly?
Usually it comes with the driver of the optical drive in Windows, and no additional increase is required.If the driver of the optical drive is not installed with its own driver, it will also be lost in optical drive.The emergence of this situation generally increases so -called optimization, acceleration programs or other programs.At this time, you can enter the security form to delete the CDROM option in the device manager, and then restart the computer, so that the system can find the driver of the new hardware reinstalled.
7. Improper use of virtual optical drives
The virtual optical drive can avoid frequent reading of the discs and improve the speed of reading, which provides the possibility for our convenient plays.However, sometimes when we do not want to use the virtual optical drive program, when we want to uninstall it or want to install the latest program, there is an unexpected. The disk format of the virtual optical drive is lost.

Basic introduction of computer optical drive
1. Data cables are connected or data cables are damaged
When the optical drive is lost, you should first check whether the data cable of the optical drive is overwhelmed and whether it is loose.If there is no failure elsewhere, and the data cable of the optical drive is often moved, at this time, a data cable should be replaced.
2. There is a conflict between the jumping line setting and the hard disk
When the jump line of the optical drive is the same as the hard disk connected to the same data cable, there will be no optical drive (maybe no hard disk). At this time, the jump of the optical drive is different from the hard disk.In order to increase the data explanation, it is best to separate the hard disk and optical drive on the two IDE interfaces.
3. Power line failure or abnormal voltage power supply abnormalities
This situation does not appear much.Because when we disassemble the optical drive or hard disk, we are too large, so that the D -type plug of the power supply is loose or because of the harsh plug of the computers working environment oxidizing and rust, the power supply of the optical drive is not normal, and the optical drive cannot be found.
4. Damage to the IDE interface
If the disk of the optical drive is lost and the optical drive cannot be used. At this time, we can exchange the interface of the optical drive with the hard disk.If you start again, you can find the optical drive, but you cant find the hard disk, which indicates that the IDE interface of the original optical drive is damaged.If the computer can start normally after switching, but there is still no optical drive, which indicates that the optical drive itself is lost. At this time, the optical drive can only be replaced.
If there is no optical drive under Windows, we can also use F8 to enter the DOS after the computer (re -start the computer instead of doS under Win98).The reason for software is mainly to find the cause from the software.Otherwise, you should consider it from the aspect of hardware.
