If the problem persists, try setting the AUTO switch OFF. This setting reduces the data
transfer rate to 150 KB/sec, making it possible to read some marginal data. Normally
the transfer rate is 600 KB/sec for the data region of the disc and 150 KB/sec for the
audio region. Always turn the drive OFF before changing the setting of the rear-panel
switches.
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. 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 standard data commands when an audio CD is in the drive will result in an
error message.
