CD and DVD not seen by XP

Archived from groups: microsoft.public.windowsxp.hardware (More info?)

Hardware componenets can do weird things. I am not sure if one device
is no longer working that it will kill the other device, but it is
possible. Have you double checked the jumper settings on the back of
the drive or tried swapping their places and make the end of the cable
Master and the Middle of the cable Slave?
