Subject: Missing CD Roms Win2k Pro

It has been my experience that patching Adaptec's ECDC can mysteriously
make CD ROM's disappear in Windows 2000 Professional. Until now I have
simply formatted my PC and reloaded Windows 2000 Professional to make
them reappear. I just recently had this happen again and this time I
actually decided that I was going to make this work again without
formatting my system again. This is what I have discovered.
Adaptec ECDC uses filter drivers to assist Windows 2000 Pro in talking
to the CDR/RW. If these filter drivers are not updated correctly they
will not load. This in turn causes Windows 2000 to not load the regular
drivers for the CD ROM's. There are still there in the Device Manager,
however you may have noticed the pretty yellow exclamation marks on
them.
To make the CD ROM's reappear you will need to edit your registry.
Before doing this I highly recommend that you make a back up of your
Registry. This is very important in the event you delete the wrong key.
Hold on tight, here we go.
After running Regedit you will want to find the following Registry Keys
and delete the following entries:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E965-E325-11CE-BF
C1-08002BE10318}
(Delete only the keys below)
UpperFilters
LowerFilters
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Class\{4D36E965-E325-11CE-BF
C1-08002BE10318}
(Delete only the keys below)
UpperFilters
LowerFilters
(You must reboot for changes to take effect)
This will keep Windows 2000 Professional from attempting to load
cdralw2k.sys and cdr4_2k. once you have deleted these keys, you may
once again attempt to load the Adaptec ECDC and Direct CD. If it so
happens that they disappear again, please repeat the steps above.

Try this (posted many time before):
This is a rather common problem when installing the Adaptec software.
Below is a solution I copied and saved from this group. It works.
Procedure as follows: (note - you may only have to do steps 7 - 10)
1. Reboot to console and logon.
2. CD to WinNT/system32/drivers
3. rename cdr4_2k.sys cdr4_2k.old
4. rename cdralw2k.sys cdralw2k.old
5. exit
6. Upon reboot I get the os back with no cdrom devices.......
7. regedit
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11
CE-BFC1-08002BE10318}]
8. delete UpperFilters and LowerFilters
9. Close regedit and reboot
10. You should get your cdrom devices back.
