Disappearing CD-ROM/CD-RW ... any solutions?
Problem: After attempting to burn a CD with nero or clonecd, my LiteOn 12x (secondary master IDE) CDRW drive disappears from Windows Explorer and My Computer. Upon rebooting, XP Pro finds new CD-ROM and asks for the XP CD to install new hardware.
Problem: After attempting to burn a CD with nero or clonecd, my LiteOn 12x (secondary master IDE) CDRW drive "disappears" from Windows Explorer and My Computer. Upon rebooting, XP Pro finds new CD-ROM and asks for the XP CD to install new hardware.
And Nero does not work right. It either recognizes the CDRW as a 1x speed or a 35x (or some crazy value) speed. And it often times will not successfully burn a disc.
All was working fine for a couple of weeks. My most recent installs was a ADS "USB Instant DVD" capture device and related software, including MyDVD authoring program (maybe the culprit??).
I also recently did the WinUpdate Roxio patch.
My other CDRom drive works fine (primary master IDE).
I had a similar problem with Win2K which turned out to be Media Player 7. When I removed WMP7, all was back to normal.
Any help with this very elusive problem is appreciated.

I sorta had the same problem..
I installed Nero but it didn't support by burner so I uninstalled it and low and behold, no cd-roms anymore, somehow Nero buggered up something in the registry and I was left up the creek without a paddle. The only solution I could I could find was to backup all my data to another hard drive, then do a fresh install of XP.
Hope you can find a better solution!!

Microsoft solution: check Windows XP Registry to find the two keys "LowerFilters" and "UpperFilters" in this Dword:
HKEY_LOCAL_MACHINE\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-0 87002BE10318}
Some programs add an extra letter in those keys and the CD-ROM disappears from Explorer. To restore CD-ROM drive access simply remove them.

I finally got my problem fixed.
My system:
Gateway 6400 server w/SCSI
SCSI HDD
Motherboard IDE: factory CDR on primary master, Liteon 12x CDRW on secondary master
Maxtor PCI Ultra100/IDE card with two HDDs.
Soundblaster Live Value
1394 firewire PCI card
No other hardware
WinXP Pro
My inconclusive findings:
1) Clean install from format did NOT fix the problem. My LiteOn 12x burner was still NOT recognized as a CDRW.
2) The "upperlimit/lowerlimit" registry fix did NOT fix anything.
3) Initial install of MS CDRW update patch did NOT fix the problem. XP burning capabilities failed at this point.
4) Uninstall of MS CDRW patch and REINSTALL of MS CDRW patch seemed to fix everything. Why would this procedure work????
Now the XP burning function works proplerly. CloneCD works fine. MyDVD works fine for burning CDs. WMP burning works fine. I am not going to try Nero or any other burning software at this point.
Maybe it is an issue with my mobo?? SCSI/IDE configuration???
Anyway, I got it working but I'm a little gunshy about tinkering with the configuration or installing more burning software until this issue is fully understood and resolved...
