Have you upgrded the Firmware in your Plextor 760? I have the EIDE
model and it was on ver 1.04 whereas they are up to 1.06.

I didn't know they had a SATA version now. There's a very similar 755SA
but no 760 listed despite what it says below!

But 1.06 says:

Version 1.06

Improvement in interchangeability when using SATA controller or
SATA/USB conversion chip.

and 1.05 says:

Version 1.05

Improved writing quality on DVD media.
DVD-R DL 8x media is supported up to 8x writing
Improved writing quality on CD media.
DVD DL Stamp Disc is supported up to 16x read while Speed Read is ON.
Improved AUTOSTRATEGY function's performance.
Improved writing performance.
Added support for Windows Vista. (Testing was done with Vista RC2. Full
confirmed compatibility with Windows Vista cannot be guaranteed until
the OS is released.)

so it would be a good idea to check -- VISTA install did not recognize
my 760 until I did go from 1.04 to 1.06
