    is my HD using DMA mode?

    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

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

    I don;t see anything about the access mode :(

    Code:
    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.
