Actually on my machine, I have 3 hard drives and a CD-RW.
Since I have all 3 drives using UDMA, I have to disable DMA on the CD-RW
to get it to burn properly.
With DMA enabled I get all sorts of problems burning CD's.
With PIO it works fine...

Why would using PIO transfers make it impossible to burn CD's? A little
while back I used to burn CD's on an old Pentium 133MHz only capable of
PIO mode 4 on all drives including the burner and it still did 8x
burning without buffer under runs. The only time that I got buffer
under runs was when I did something that caused heavy disk access for
more than a couple of seconds (like loading netscape). Sure UDMA is
better, but is it essential? (I have never had a buffer under run on my
current Linux box using UDMA even when the system is being hammered by
several processes.)
