Missing CD Drivers - Possible Fix

Hi All,

Think this might help a few people..!

Nero 5 problem still present (disappearing CD Drives) when CDRWin NOT installed. Only fix found, but not fully tested. Now using Roxio flawlessly and given up on Nero completly..?%^*

Not my fix, just one I found.

"This problem is caused by an association created in the system registry between these specific Adaptec driverfiles and the CD file system drivers for Windows 2000. If the Adaptec driver files are renamed or removed, then the system will loose access to any CD drive (CD ROM, CD
recorder, or DVD).

1. Go to the RUN line and type in Regedt32 and press Enter.
2. Go to the following registry locations and delete the
key values for UPPERFILTERS and LOWERFILTERS: (Do NOT
delete the entire 4D36E965-E325-11CE-BBFC1-08002BE10318 key)
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E965-E325-11CE-BB FC1-08002BE10318}
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Class\{4D36E965-E325-11CE-BB FC1-08002BE10318}
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11C E-BFC1-08002BE10318}
4. Close out of Regedt32.exe and reboot the computer.
5. You should have access to your CDROM drives after reboot."

I've seen this problem too.

you can also boot off of the xp cd and repair the current installation.

it will find that the cdfs.sys, and two others (can't remember them) have been changed and restore the original copies from the cd..this helped in my case. just FYI.
