Hiya, Before i lost a hd due to a trash! My Pioneer A04 was burning dvd's quite happily in UDMA Mode 2. After the re-install of WinXP, I can no longer use the dvd writer in this mode! It writes the lead-in and then quits! However, if I run the drive in PIO Mode 4, everything is fine! I have updated to the latest ASPI drivers (4.711) and still the same! This is annoying the hell outta me as it used to run fine in UDMA mode! Anyone else here have similar probs and got a fix? T.I.A.
