My Windows XP SP2 No Longer Detects my dvd-rom drives. I have 2 dvd rom drives, one is a DVD-Rom and the other is a DVD+-RW rom drive. They were working right and detected good for a while, but all of a sudden neither one of my rom drives are being detected. They have yellow ? buy them, and it says the information in the registry is corrupt, or invalid driver, please reinstall drivers.

1. Start Registry Editor (regedit.exe).

2. Locate the UpperFilters value under the following key in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

3. On the Edit menu, click Delete, and then click OK.

4. Locate the LowerFilters value under the same key in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

5. On the Edit menu, click Delete, and then click OK.

6. Quit Registry Editor.

NOTE: After you remove the Upperfilters value and the Lowerfilters value, if you notice lost functionality in a particular program, such as CD recording software, you may need to reinstall that software. If the problem recurs, consult with the software vendor for assistance.

7. Restart your computer.

Same solution as Jeremy but with an automatic .reg file

REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}]
"UpperFilters"=-
"LowerFilters"=-

[-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdr4_2K]

[-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdralw2k]

[-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdudf]

[-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UdfReadr]

In device manager uninstall driver then use scan for device option in device manager it will resolve your problem. If problem remain then change IDE of drives IDE1 device to IDE2 and IDE2 device to IDE1 .
