i found this..
"Dear PC: I have a CompUSA PC using Windows ME. When I try to use
the CD-ROM drive, it seems to not be able to read the disc, and a
message pops up to please insert a disc into drive E (which is the
correct drive). I have researched all over to try to troubleshoot
it myself to no avail. Can you point me in the right direction?

Dear Josh: I hate to say this, but that's usually a sign that the
drive is ready to be replaced. New CD-ROM drives are fairly
inexpensive. Sorry I couldn't give you better news on a Monday.
Happy computing!"
