Section 4: Maintenance and Troubleshooting
10. The drive begins the diagnostic routine, and the WRITE H and WRITE L
indicators alternately blink. The diagnostic routine takes approximately nine
minutes. Upon completion of the diagnostic, you see the results:
Y
Disc ejects: If there was no problem, the disc is ejected automatically.
Discard the disc. It cannot be reused.
Y
Blinking WRITE H indicator LED: No blank disc.
Y
DISC indicator LED blinks once: Write or read error.
Y
DISC indicator LED blinks twice: Initialization error.
11. If the disc was not ejected automatically, press the stop/eject button to eject the
disc.
12. Turn off the computer power.
13. Remove the spare jumpers you installed in step 5 above, and replace the jumper
across the TERM pins (if you removed it for the test).
14. Reconnect the SCSI cable to the PlexWriter drive. If you removed the drive to
gain access to the cable or jumpers, replace the drive in the computer. Then
replace the computer cover.

Performing the Self-Test on an External Drive

This procedure details how to perform a self-test procedure on an external drive.
What you'll need:
To perform the test you'll need:
• A blank piece of Plextor-recommended CD-R media for the CD write/read test.
(See "Recommended Media" on page 41, or visit our web site.)
To perform the CD write/read test:
1. Turn the PlexWriter power switch OFF.
2. Turn the computer power OFF.
3. Carefully unplug the SCSI cable from the PlexWriter by pulling the cable gently
rearward.
4. Note the position of the DIP switches at the rear of the PlexWriter. Write down
the switch positions. (You'll need to change these switches for the test, but you'll
want to return to the same configuration after the test and leave the PlexWriter's
setup the way you found it.)
