Recently installed a Plextor PX-320A CDRW/DVD combo on my XP Home machine. No problem installing the drive or Roxio CD Creator 5.0 (which does not support XP but I patched to 5.3 which does), however I'm not able to format CDRW media correctly. The disc fails to complete the format and I have to shut down CD creator (even left the format working overnight) Tried Memorex and Verbatium/high speed discs to no avail. I updated the Plextor firmware. Writer is sitting alone as master on secondary IDE. DMA is enabled as available in XP. I have not run the Plextor self-diagnostics, but DVD and CD functions seem to work correctly. Any ideas would be appreciated.
