I too have this same problem, with my cd drive, and with my dvd-r drive. My dvd drive stopped working first, says no disc is in the drive, then several months later, my cd drive was not recognizing more and more cd's. Now it seems to only read one, once in a great while. I can hear the drives spinning, but then nothing, and it says no disc in drive. I too am using XP, and have made no changes to my system prior to them going out..any ideas?
