FAQ, tips and tricks - Installation




- How come that the Plextor drive does not get power?

On ATAPI systems:
- The Power connector is not attached or malfunctioning. When the Computer's power is turned ON (no CD/DVD in the plexwriter), the Plexwriters LED should be illuminated briefly and then extinguished. After startup on Atapi models, the green light should be OFF when no CD is loaded and ON permanently when the CD is loaded.

On SCSI systems:
- The Power connector is not attached or malfunctioning. When the Computer's power is turned ON (no CD in the plextor), the Plextor ON LED should illuminate. When a CD is loaded, the DISC-LED should be on. The ON-LED is flashing when reading the CD is in progress. The L-LED and H-LED indicate that Low-speed or High-speed writing is in progress.

On USB systems:
- The Power connector is not attached or malfunctioning. Important: use only the supplied adaptor to power the USB drive, other power adaptors may damage the drive which is not covered in warranty.
- The power supply is not connected and/or plugged in. When the power is on and no USB cable connected you should be able to open and close the tray using the eject button. When the USB-drive is connected and powered on, the green led should be on permanently, regardless if there is a CD loaded or not.

On USB-slim line devices, like PX-S88TU and PX-S2410TU the LED is flashing when powering on and is extinguished when the CD is loaded.

-It is recommended to use the secondary MASTER position to have the best performance.
-Ensure you installed the latest IDE driver for the IDE controller on the motherboard, this can be found on the website of the manufacturer of the motherboard.

- Can I install my Plextor PX-708A into an external usb2.0 / Fire Wire box?

The Plextor internal units are designed to operate inside a pc connected to a normal IDE controller port.

Should you experience any problem with such a setup in an external usb2.0/FW box.
We can advice you to either purchase the PX-708UF (the external version of the PX-708A) or to contact the manufacturer of the external box so they can resolve your problem.

- Is the PX-712SA, with serial ATA interface, compatible with every Motherboard that has SATA interface ?

The PX-712SA works on most motherboards when equipped with Serial ATA interface (SATA), however, one should check with the manufacturer of the motherboard if the SATA supports optical devices. In some cases the SATA controllers do need a BIOS upgrade to support optical devices other controllers do not support it at all.
