Was getting errors with my Khyperion DVD+RW drive and tried to update the firmware. Afterwards, every time that I would put a blank DVD in, it would only recognize it as a CD. I have tried making the drive the only one, uninstalling my burner software (all 3), uninstalling the drivers, doing a repair install of WinXP Home, swapping out IDE cables, putting the DVD on IDE channel 1, and probably a few other things. Finally, I decided that I must have fried the drive so I bought an NEC drive. It has the same problem.
