you've look for errors in event viewer? (eventvwr.msc)...
You'll check what it's the status of the drive in disk administrator... if
it appears there...

What may have happened is that you have installed it on the secondary
IDE connector, not previously in use, and that this has been disabled -
the standard IDE disk controllers in XP don't provide any longer for
disabling one channel, but you may have different ones, and it would be
worth looking in that part of Device Manager
