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 60.
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 Audio
CD play mode, see Chapter 11. Since audio compact discs do not have
computer data, typing computer commands while a CD-Audio disc is in your
drive, will result in an error message.
