Section 5. Maintenance and Troubleshooting
7. Insert a blank Plextor-recommended DVD±R or CD-R disc. Be sure
to use only media of the type recommended by Plextor.
If the LED indicator blinks amber three times, the loaded disc is
not a blank DVD±R or CD-R disc. Remove the disc and insert a
blank, Plextor-recommended DVD±R or CD-R disc.
8. The drive begins the diagnostic routine. Upon completion of the
diagnostic, you see the results:
If there was no problem, the disc is ejected automatically.
If there was a problem, the disc is not ejected, and you see the
LED indicator blink green:
One green blink indicates a write or read error.
Two green blinks indicate an initialization error.
Three green blinks indicate the disc is not blank or cannot be
detected properly.
9. If the disc was not ejected automatically, press the eject button to
eject the disc.
10. Turn off the computer power.
11. Reset the self-test/DMA jumper at the rear of the PX-760SA to its
original setting as noted in Step 3 above.
12. Reconnect the SATA interface cable to the PX-760SA 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.
If you discover a problem with the PX-760SA drive, do not attempt to
service the drive yourself. Contact us to get an RMA number and take
steps to return the drive to Plextor. See "Returns" on page 91 for details.
