Drive Not Terminated
If your CD-ROM drive is the only SCSI peripheral attached to your computer or is the
last SCSI peripheral in a daisy chain (i.e., a cable connecting multiple SCSI peripherals
to a single SCSI interface board), check that its termination switch is ON. Always turn
the drive OFF before changing the setting of the rear-panel switches. See Chapter 7.

Additional Symptom

CDR101----Not Ready
Reading Drive [X]
All Commands Sent to the Drive
Result in CDR101 Error
Possible Causes and Solutions
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
standard data commands when an audio CD is in the drive will result in an error message.
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 card for recessed, broken, or bent pins. If a
ribbon cable is used, inspect for any signs of distress, such as kinking.
