Troubleshooting SCSI Problems
Symptoms
Error messages such as the following upon initial installation of the PlexWriter drive
and device driver software:
•
“Invalid device specification”
•
“No device found”
•
“No SCSI interface board found”
•
“No response from SCSI interface board”
•
“No drives in use”
Possible Cause #1
•
Improper SCSI device driver installation. Your computer needs a SCSI device
driver to link the SCSI interface board to the PlexWriter drive.
Solution #1
•
Obtain the latest available SCSI device driver from the SCSI board’s
manufacturer or the manufacturer’s web site. Then install the updated driver in
your computer.
•
Remove device support from the operating system and attempt to re-install the
SCSI device driver.
•
Make sure there are no hardware conflicts with another board in the system. Such
hardware conflicts can prevent the SCSI device driver from loading.
Possible Cause #2
•
Improper SCSI bus termination.
Solution #2
•
Ensure that only the peripheral at the end of the internal SCSI cable and/or the
last peripheral in a SCSI chain of external devices is terminated. See page 13.
•
Some peripherals have a setting marked “Termination Power” instead of
“Terminator.” Ensure that termination power switches are set correctly.
