If anyone out there can help I'd be most grateful!
I have 'lost' my DVD and CD R/W drives in the sense that they do not appear in My Computer and I xan not access them. Device manager shows then as present, but with adjacent exclamation marks in yellow circles. I've tried uninstalling and reinstalling them using the add hardware manager, but this results in an error Code 39 message. The drives do show in BIOS as Primary slave and Secondary master (or similar, from memory).
I've trawled help sites, but have no been able to solve the problem, which first ocurred after I'd tried to run downloaded CD burners (there is a problem with the installer in my XP Pro, and I have been unale to install some programs). I have checked the relevant registry entry (HKEY_LOCAL_MACHINE........../Class/4D36e965........10318), but there are no UpperFilter or LowerFilter entries there, so the fix that many people seem to have found is not available to me, alas!
The XP pro I have installed is, unfortuneately, illicit (it was installed last year in desperation to try to get the CD re-writer working for a very urgent task). I have bought a legal copy now, but of course can't use it until the drives become visible again.
Any help, please, much appreciated.
