Drive Not Terminated
If your CD-ROM drive is the only SCSI peripheral attached to your computer or is the

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.
