Installed Windows VHP32 on my Asus P5B Deluxe and it was a easy install. Used a Plextor PX755SA (SATA) and every thing worked great. Tried to install my Asus disk for the chip set drivers and it would have nothing to do with that. But every things working. Few days ago while trying to get some DVD burning software to install, (Roxio 7.0 that comes with Plextor won't work) the Plextor stops working, no drive letter. I tried it in a deferent SATA slot with no luck. Pulled it and stuck in an older IDE Plextor and the same thing. Device Manager says it's not working correct. Plextor.com has nothing for Vista or Roxio.com. Anybody else having problems? I'm going to try the SATA Plextor on my XP machine and see what happens. TIA SDR
