1st, I have a HD install of Knoppix
I noticed on bootup it said something about PIO mode 33 use DMA=xx or something like that. . .
I just wondered id anyone knew how to check my hardrive's DMA modes. . .
Thanx

sudo hdparm /dev/hda
The default situation after a hd install won't allow you to sudo though so you probably should do:
su
hdparm /dev/hda

thanx for the quick reply
they both worked and DMA says it's on
I don;t see anything about the access mode :(
root@Knoppix:/home/christopher# hdparm /dev/sda
/dev/sda:
readonly = 0 (off)
geometry = 39083/64/32, sectors = 80043264, start = 0
So how can I know if DMA is on?

SCSI drives do not need DMA enabled the controller it connects through takes care of the speed of the connection.
Thought this might be the case after posting; thanks for the confirmation.
