PlexWriter 8/2/20 Operation Manual
2.
Run the test (diagnostic) program that is probably included with the device
drivers for your SCSI interface board, following the instructions given in the
SCSI interface board’s manual.
3.
If the information provided by the error message and test program is not
sufficient for you to fix the problem, go to the troubleshooting information
below.
NOTE:
Because different SCSI interface boards generate differently worded error
messages, the messages displayed by your computer may differ from those shown
on the following pages.
If you have problems during or right after installation of your PlexWriter drive, use
these charts to help find the problem. You can also use these charts to help find
problems that develop in existing installations.
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 software
device driver to link the SCSI interface board to the PlexWriter drive. If this
driver cannot be loaded properly, an error message is displayed on the computer
screen.
Solution #1
1.
Reboot the computer.
2.
Watch as the CONFIG.SYS file executes, and look for an error message to
appear.
3.
If necessary, press the Control and S keys simultaneously to freeze the display.
(Use the Control-S combination again to continue.)
If the SCSI device driver cannot be loaded properly, either a software or hardware
conflict exists.
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.
