Plextor PX-755UF Installation And User Manual page 39

3. If you have a PX-755UF drive that is not recognized in Windows:
a) If your USB or IEEE 1394 controller has a yellow diamond with
an exclamation point (!), contact your PC or motherboard
manufacturer for help, and to troubleshoot your controller for driver
compatibility or conflicts. It may just be a matter of obtaining the
latest driver, or a motherboard BIOS update, from the manufacturer.
b) If the USB or IEEE 1394 controller is listed and does not have a
yellow diamond with an exclamation point, but the Plextor drive is
listed as a "USB" or "IEEE 1394 Storage device," select the
"Storage device" and then select the "Remove" button. Reboot your
system. The system will do another hardware scan and should install
the driver properly.
4. If you still have problems, or if the USB or IEEE 1394 controller is
listed and does not have a yellow diamond with an exclamation
point, but you do not see the Plextor drive listed as one of the
devices, contact Plextor Technical Support. (See "Appendix B:
Technical Support" for the different ways you can contact us.)
