Moef, Here is the instr. from the 755-[B]SA[/B] manual. I’m guessing to replace the SATA reference with IDE.
Using the PX-755SA Self-Test Diagnostics
The PX-755SA drive contains a set of self-test diagnostics that can help
isolate trouble and determine if a problem is in the drive or elsewhere.
NOTE: Using the self-test diagnostics requires opening the computer and
adding a jumper to the rear panel of the drive. If youâ€™re are not
comfortable with opening your PC and adding a jumper, you may want to
let someone with more experience handle this aspect of troubleshooting
To perform the tests youâ€™ll need:
â€¢ Tools to remove the computerâ€™s cover
â€¢ A jumper (supplied)
â€¢ A blank piece of Plextor-recommended DVD+R, DVD-R, or CD-R
media. (See page 47 or visit our web site.) The self-test will write to
this media, so you wonâ€™t be able to use this disc again.
This tests three functions of the drive: writing at maximum speed,
continuous playback at maximum speed, and random access.
To perform the self-test:
- Turn the computerâ€™s power OFF, unplug it from its power source,
and open the computer to gain access to the rear of the PX-755SA
drive. Typically, this involves loosening or removing several screws
on the back panel of your computer and sliding off the cover. (See
Figure 4 for an example.)
CAUTION: Before you attempt to open your computer be sure to
properly ground yourself by wearing an anti-static wristband. This will
help prevent static damage to your computer system.
You should be able to see the back of the PX-755SA drive connected
to the SATA cable and power connector. There are two cable
connections to the drive: the left-hand connection is a 15-pin SATA
power cable. The right-hand connection is a 7-pin SATA interface
NOTE: You may have to remove the drive from the computer to
perform the next two steps.
Hold the SATA interface cable (the right-hand cable) at its
connection to the PX-755SA drive. Carefully remove the SATA
cable from the drive by pulling the cable gently rearward. Leave the
SATA power cable attached to the drive.
Note the self-test/DMA jumper at the rear of the PX-755SA. If no
jumper is installed, place a jumper across the two pins.
Figure 21: Add the PX-755SA self-test/DMA jumper to
enable the self-test diagnostics
If you removed the drive for access to the cable and self-test/DMA
jumper, slide it back into the computer and reconnect the power
cable to the drive. (Do not connect the SATA interface cable.)
Replace the computerâ€™s cover and re-connect the computerâ€™s power
cord to the power source.
CAUTION: Turning on the computer power without first replacing the
cover can be dangerous to the computerâ€™s components and also to
you. Be aware of the danger of electric shock and do not touch any
components inside the computer.
While pressing the PX-755SAâ€™s eject button, turn the computer
power on. The driveâ€™s LED indicator blinks green, then amber, and
the tray ejects.
Insert a blank Plextor-recommended DVDÂ±R or CD-R disc. Be sure
to use only media of the type recommended by Plextor.
ô€‚‰ If the LED indicator blinks amber three times, the loaded disc is
not a blank DVDÂ±R or CD-R disc. Remove the disc and insert a
blank, Plextor-recommended DVDÂ±R or CD-R disc.
- The drive begins the diagnostic routine. Upon completion of the
diagnostic, you see the results:
ô€‚‰ If there was no problem, the disc is ejected automatically.
ô€‚‰ 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
If the disc was not ejected automatically, press the eject button to
eject the disc.
Turn off the computer power.
Reset the self-test/DMA jumper at the rear of the PX-755SA to its
original setting as noted in Step 3 above.
Reconnect the SATA interface cable to the PX-755SA 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-755SA 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 â€œReturnsâ€ on page 57 for details.
