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 12). However, 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.

Possible Causes and Solutions
Drive is Not On
If you have a PX-45CH external drive, check that its rear-panel power switch is ON.
If the drive is the PX-43CH internal model, ensure the power cord from your
computer’s power supply is plugged firmly into the drive power conector.
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.
Improper SCSI Bus Termination
Ensure that only the last peripheral on the SCSI bus is terminated (see Chapter 7).
Some peripherals have a setting marked ‘‘termination power’’ instead of ‘‘terminator’’.
Ensure their termination power switches are set correctly.
