Stuck in PIO problem, only slightly different. I also am using Windows XP pro, although i know how to get it forced into DMA. I have done what is needed to get it into UDMA2 but when I do that, the drive (Plextor PX-708a) will not read any disks. It just leaves endless messages in the event viewer about "so and so device did not respond within the timeout period". I think I've just about tried everything to get around this but continue to have these problems. I actually did an entire rebuild of XP with the current 1.04 firmware and it still did it. Bought and tried another controller card, with the same results. Any ideas or insights would be much appreciated. PIO mode just takes so long to burn even though I have perfectly sound copies and a 100% buffer all the time.
