12.2 PC Compatibles: Existing Installations

Symptoms
• Invalid drive specification
• No device found
• Drive not responding
Possible Causes and Solutions
Drive Is Not On
If you have a PlexWriter external drive, check that its front-panel power switch
is ON. If the drive is the internal model, ensure the power cord from your
computer's power supply is plugged firmly into the drive power connector.
Power is applied correctly if one of the front panel LEDs are on.
Bad Connection Between the CD-R 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 peripheral at the end of the internal SCSI cable and/or the
last peripheral in a daisy chain of external devices is terminated (see Chapter
7). Some peripherals have a setting marked "Termination Power" instead of
"Terminator." Ensure that termination power switches are set correctly.
