Using the PX-755UF Self-Test Diagnostics

The PX-755UF contains a set of self-test diagnostics that can help
isolate trouble and determine if a problem is in the drive or elsewhere.

What You'll Need

To perform the tests you'll need a blank piece of Plextor-recommended
DVD+R, DVD-R, or CD-R media. (visit our web site.) The self-test will
write to this media, so you won't be able to use this disc again.

Performing the Self-Test

This tests three functions of the drive: writing at maximum speed,
continuous playback at maximum speed, and random access.
To perform the CD write/read test:
1. Unplug the USB or FireWire cable from the rear of the Plextor PX-
755UF drive.
CAUTION: Failure to disconnect the USB or FireWire cable before
starting the test could result in system data loss.
2. Set the PX-755UF drive's power switch to OFF (so the "0" is
depressed).
3. While pressing the eject button, set the PX-755UF's power switch to
ON (the "1" is depressed). The front-panel disc/busy indicator blinks
green and amber, and the disc tray opens.
4. Insert a blank Plextor-certified DVD+R, DVD-R, or CD-R disc. Be
sure to use only media of the type recommended by Plextor. Then
close the disc tray.
If the disc/busy indicator blinks amber three times, the loaded
disc is not a blank DVD+R, DVD-R, or CD-R disc. Remove the
disc and insert a blank, Plextor-certified recordable disc.
