cd roms disappeared

[ai42]

Ok I'm a pretty good technical genius and I know what I am doing for the most part. But my CD drives dissappeared in Windows. They were functional before (yesterday actually was watching a DVD), then today nothing. The drive letters won't even show up. The BIOS recgonizes it correctly and everything seams fine. In my HW profiles (win2k SP2) it says a code 19 and that my registry might be corrupted. The only thing I did today was install RealPlayer and LiquidAudio, I uninstalled them both hoping that it was the installer but still nothing any ideas? BTW my HW is in my sig. I know a reinstall if win2k should fix this but that is a serious pain the arse.

BTW I tried to uninstall and reinstall them both (DVD and CDRW) in the windows profiles and still the same error. Also ran Norton WinDoctor to fix any registry errors and nothing there either. Also manuelly edited the registry to remove all realplayer and liquid audio entries (after the uninstall).... this is pissing me off im considering a reinstall but that is a pain.... The CD drives work in DOS btw, just stupid windows...

Yet another reason to hate windows and microsoft as well.

EDIT: hehe no sig on this msg board, copied and pasted it (as nobody is on that msg board at 1am) anyway system is as follows:
AMD 1Ghz (266FSB)
MSI K7T Turbo R
2x 256MB Micron PC133
Jaton GeForce 2 MX 32MB
VisonTek TNT2 Vanta 8MB PCI (duel display)
SB Live MP3+
3Com 10/100 NIC
2x 30gig WD HDs (RAID 0)
IBM 75GXP 45 Gig
Delta 12x DVD
12.10.32 Lite-On CDRW
LS-120


pretty much it... got more but it isnt relevent (not that most of that wasn't anyway)

Use Regedit and find the following keys:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

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


(these keys are generally mirrors of each other, but go to each one individually for the following procedure):

Now, under each of these keys is a value for UpperFilters and LowerFilters. Delete the value contained in each of these filter keys. So, you'll be deleting 6 values total for these 3 keys (2 values for each key, an Upper and a Lower Filters value).

Do NOT delete the actual Upperfilter and Lowerfilter keys themselves...just delete the values contained within them. Reboot. Cdroms should be back.
