Resim zrovna neco podobnyho, a nevim ja DMA zapnout:

alnagon:~# hdparm /dev/hdb

/dev/hdb:
  multcount    = 32 (on)
  IO_support   =  0 (default 16-bit)
  unmaskirq    =  0 (off)
  using_dma    =  0 (off)
  keepsettings =  0 (off)
  readonly     =  0 (off)
  readahead    =  8 (on)
  geometry     = 131/255/63, sectors = 2116800, start = 0

alnagon:~# hdparm -d /dev/hdb

/dev/hdb:
  using_dma    =  0 (off)
alnagon:~#
alnagon:~#
alnagon:~# hdparm -X -d1 /dev/hdb

/dev/hdb:
  setting using_dma to 1 (on)
  HDIO_SET_DMA failed: Operation not permitted
  setting xfermode to 0 (default PIO mode)
  using_dma    =  0 (off)
