There is no problem with the Win 7 optical drive letter

win7 version 7600 I don't think it's very easy to use, it's just a little more functional, it may feel very comfortable, but it's actually not easy to use, it's inconvenient, it's actually complicated the system, I suggest you still use XP is very stable. You always have such and such small problems with win7, I suggest you wait for it to be stable before using it, because I have used this before, and I feel it deeply.

What motherboard are you?

Go to the corresponding official website to find the driver.

This is due to a hardware failure or conflict that prevented the system from detecting the CD ROM at boot time. It is characterized by the fact that before the advent of the Windows graphical interface, the system detected that there was no CD ROM in the hardware device.

This phenomenon of "loss" of optical drives generally occurs after the user opens the chassis and plugs in the hardware device or sets up the CMOS. Therefore, the way to recover the optical drive is to check the hardware in the following order:

If the optical drive is connected to the second IDE port, check whether the second IDE port in the CMOS is open. Because of the number of touches, some motherboards can manually close the second IDE port.

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

Whether the jumper settings of the optical drive are correct, mainly for the newly installed second optical drive or if the optical drive is changed from two optical drives to one.

Check whether the data cable of the optical drive and the IDE port used by it are damaged. The author has encountered the situation that the second IDE port is damaged, resulting in the loss of the optical drive. During the inspection process, you can swap the IDE interface with the hard disk, exchange the data cable, and connect it to the hard disk at the same IDE port to check whether the system can detect the CD ROM when the computer is turned on.

After the above 4 checks, the system can detect the CD ROM device after powering on and restarting the machine (if it still can't be detected, you should consider talking about the CD-ROM drive is broken).

The specific operation method to solve the problem of win7 optical drive not reading disk is as follows:

1. Win+R open and run, enter regedit.

Locate the following path key locations:

burning\staginginfo\volume。

1. Win+R runs to open the local service manager.

3. Right-click on this service - Stop and Disable.

4. The reboot takes effect.

3. Modify the registry.

1. Run the registry "regedit" as follows: hkey current user software microsoft windows currentversion explorer cd burning staginginfovolume, 2. and then right-click stagingpath="an arbitrary valid path in the right box (the default is c:users( Your username: AppDataLocal, Microsoft, Windows, BurnBurn)".

3. Use variables: %userprofile% local Microsoft Windows burn burn

4. After saving, close the registry and the problem is solved without restarting.

Click: Devices with removable storage, and it will be displayed.

You can use the getdrivetypea function to crack,It should be your win7 is genuine,In order to prevent users from copying the system to multiple machines for use。

It should be that there is no drive letter defined, set it up:

1. Right-click [My Computer] [Manage].

2. Select [Storage] [Disk Management], right-click [CD-ROM] and select [Change Drive Name and Path].

3. Click [Change].

4. Click [Assign the following drive letter] Select any letter in the drop-down box and click [OK].

Should you check the hardware first, open the main chassis, and see if the power and data interface cables connected to the optical drive are not plugged in? If you plug it in, start the computer, the optical drive indicator light is on, indicating that the optical drive can be detected, if there is no drive letter, it means that the optical drive may be broken, so you have to find after-sales. Hope it helps.

Control Panel Administrative Tools Computer Management Storage Disk Management.

Then the Actions menu of All Tasks changes the drive letter and path.

1. Is there an optical drive in the BIOS? No re-changeovers;

2. There is in the BIOS, but there is none in the system, the device manager deletes the IDE channel and controller, and reboots. ok！

The problem with your motherboard, or the interface.
