Drive Not Resetting
In some cases, even if you restart the computer by pressing its reset button or the
Control, Alt, and Del keys simultaneously, the drive does not appear to respond. Try
turning the power switches on the drive and computer OFF, then ON. This complete
shutdown should fully reset the drive and computer.

Possible Causes and Solutions
Defective CD-ROM Disc
A fingerprint, contaminants, or deep scratches on the disc’s surface may prevent the
drive from reading data. Read Chapter 10 to learn how to clean CD-ROM discs.
You should also review the low performance symptom discussed on page 57.
Bad Connection Between the CD-ROM Drive and the SCSI Interface Board
Inspect the cable, drive, and interface board for recessed, broken, or bent pins. If a
ribbon cable is used, inspect for any signs of distress, such as kinking. Ensure the red
stripe side of the ribbon cable plugs into pin 1 on both the drive and the interface board.
Audio CD Disc in the Drive
Plextor CD-ROM drives are capable of playing high-quality audio when used with
appropriate audio playback software, or when the drive is set to Music CD Player
Mode (see Chapter 11). Since audio compact discs do not have computer data, typing
computer commands while an audio CD is in your drive will result in an error
message.
