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 PX-20TSe external drive, check that its front-panel power switch is ON.
If the drive is the PX-20TSi 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 is on.
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.
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
their termination power switches are set correctly.
