My daughter, running Win98, has been writing to CD-R discs quite happily until now when the PC is claiming that the CD Writer is not accessible. Inspection shows that it is seeing all discs as full, even new ones known to be empty. I have tried another writer that I know to be good but the same thing happens. If anyone knows where to look next I should be very grateful.
Ooops - quite right. Too used to working with re-writables. First point - can the writer read a CD? If it does, could be the write heads need cleaning. If OK, check your drivers. Insert your OS CD into the drive and <run> sfc /scannow.
If not, move on to the next point. Does the writer show up when the PC is first booted (POST screen). If not, suspect your data cable, or connection to the mobo (rule out conenction to the drive if you've already tries more than one drive. Does the CD light come on during boot-up? If not suspect power supply.
