This site article, "Problems - ?My CD drives have vanished (from Explorer, Device Manager, etc.)", explains that this happens quite often if a third-party CD/RW package has been uninstalled that had added references in the Windows Registry for modules which they use, and these references were not removed. The suggested fix is downloading and using the Registry patch "CDGone.ZIP."
XP is not finding CD or DVD drive. (E or F)
It finds my two hard drives (C & D). They have always showed up on explorer before. On entering setup (BIOS?) it show the drives there.
System ? Hardware shows them with a yellow ! over them, Any ideas guys?
