Troubleshooting for Macintosh Users
Symptom
Possible Causes
Solutions
Drive will not
operate as CD-
ROM, CD-R or
CD-RW
device.
Whether using the
PlexWriter as a
standard CD-ROM,
CD-R or CD-RW
device, you will need
additional software and
device drivers that are
not part of the
Macintosh operating
system.
You will need to purchase additional
software. Supported software lists
can also be found on the Plextor web
site at www.plextor.com.
Drive does not
respond.
Bad connection
between PlexWriter
drive and USB
interface.
Ensure the USB cable is securely
connected between the computer
and the PlexWriter, and that the
cable is not damaged.
Using the Self-Test Diagnostics
The PlexWriter contains a set of self-test diagnostics that can help isolate trouble and
determine if a problem is in the PlexWriter drive or elsewhere.
The self-test consists of a CD write/read test.
What You’ll Need
To perform the self-tests you’ll need a blank piece of Plextor-certified CD-R media.
(See “Recommended Media” on page 39, or visit our web site.)
CD Write/Read Test
This tests three functions of the drive: write, random access, and verify.
To perform the CD write/read test:
1.
Unplug the USB cable from the rear of the PlexWriter.
2.
Set the PlexWriter’s power switch to OFF (so the “0” is depressed).
3.
Set the self-test switch to SELF TEST.
4.
While pressing the eject button, set the PlexWriter’s power switch to ON (the “1”
is depressed). The front-panel LED indicator blinks green and amber.
