Well my point was that I burned some perfectly good CDs on an HP 2100 burner under Win98. I moved that burner to a machine running Win2K, those CDs were unreadable. They weren't that important so I put them aside to try some data recovery at a later time. I acquired a DVD burner, that was put into the Win2K machine, and the HP 2100 was returned to the Win98 machine. A while later I came across the unreadable CDs and decided to try to recover the data. They worked the first time in the Win98 machine, the Win2K machine still can't read them. Software and Drivers...
