What's the most likely cause of a CD-RW not showing up in Explorer and not working when using Nero? This old optical drive I put in someone's computer opens the tray fine, and the light comes on - it just doesn't show up or do anything after that. I would have thought it unlikely that the IDE cable has come loose, but if nobody can think of any other ideas, I'll have to try it.

The difficulty is this computer is some distance away
