this guy gave me his pc to cleanup, one problem was couldn't see the dvd/cd drives -they had exclamation marks in device manager and it was complaining that it couldn't find them

spent about 15 mins trying different ide cables and drives
this is what fixed it

hp site
go to device manager, click uninstall on the cd drives
#
Click Start, Run, and type the following into the Open field: regedit
#
Click OK. The registry editor appears.
#
In Windows XP, click File, Export, type a filename that is easy for you to remember, and click Save.
In Windows 2000, click Registry, Export Registry File, type a filename that's easy for you to remember, and click Save.
A copy of the registry has saved for back-up purposes.
#
Click the plus sign ( +) next to the following items in the list:

* HKEY_LOCAL_MACHINE
* SYSTEM
* CurrentControlSet (or the current control set with lowest number if that is all that is listed)
* Control
* Class

#
Select 4D36E965-E325-11CE-BFC1-08002BE10318.
#
Select UpperFilter in the right window and press the Delete key.
Confirm the deletion by clicking Yes.
#
Select LowerFilters in the right window and press the Delete key.

go back to device manager, and click scan for hardware changes, and they'll show up :)

itunes is good at causing this.

had some p2p sw like limewire/napster cause it too.

it's them messing up when trying to install their cd writing features :/

edit: deleting just upper filters does it when it's itunes that has caused it. otherwise you might find your self deleting lower filters too (and having some cd writing softare not working till you reinstall it (as long as it wasnt the reason lol)).

I had a problem like that on a newly built pc about a year ago using MCE2005. I think the fix was the same, and it seemed to be caused by corrupt RAM in my case.

Does this work in vista thats not been installed over the top of XP?

In device manager it just doesn't show up the drive at all once it's vanished.

If i reboot a couple of times it comes back (sometimes)

There is an article on the Microsoft website that deals with This issue, it does not state that it refers to any particular OS, so it probably would work in Vista.
