i have a tdk burner. It doesnt burn correctly. Its like, it reads for a second or two, stops reading for several seconds, then starts again for a second or two...nothing really burns. APparently, after calling tdk, they said that xp is being the problem. It switched the drives in that channel to PIO mode, while they SHOULD be in DMA mode. How do i go about changing the modes back-to DMA?
