I just did that to my CD player and to my horror it said that DMA was
NOT on ! Can't believe it, I never had to complain of anything with my
drive. Now I am wondering, maybe I would be even happier if I could turn
it on ?! :o)
For example when I ripped all my CD's, I got about x4 speed, which was
perfectly fine by me, but I read on this list that people find this slow
and manage a lot more with DMA ?! That may also fix my problem with DVD,
some times it's jerky, and I read here too, that it could be due to lack
of DMA.

So I read "man hdparm", and then tried a "sudo hdparm -d /dev/hdc"

But then when I check back, DMA is always off, it won't come one.

How is one supposed to proceed to enable DMA on a bloody CD drive ?
