I keep having this problem on a daily basis where my Primary IDEChannel transfer mode keeps switching from Ultra DMA Mode 6 to PIO Mode, and when it is in PIO mode it slows down the computer overall, anyone knows what could be causing this problem?
From what I've read here and there, XP SP2 will switch to PIO automatically when it encounters a bad block on a CD/DVD. This is to ensure that the system still runs efficiently.
Maybe you're trying to read a bad disk?
I have had problems like this with a DVD Burner and had to re-flash it..

There simply are many problems which will cause DMA to switch to PIO, such as bad cables, BIOS setups, and such. Google "dma mode keeps switching to pio" if you want, and see what others have done in attempts to solve their problems.
Another thing I saw was that Daemon tools could cause such a problem. You wouldn't happen to have that installed on your computer, would you?
