DMA isn't enabled, try again (hdparm -d1)

thats too slow
  hdparm -tT /dev/hdb

/dev/hdb:
  Timing buffer-cache reads:   128 MB in  0.75 seconds =170.67 MB/sec
  Timing buffered disk reads:  64 MB in 36.39 seconds =  1.76 MB/sec

hdparm /dev/hdb

/dev/hdb:
  HDIO_GET_MULTCOUNT failed: Invalid argument
  I/O support  =  0 (default 16-bit)
  unmaskirq    =  1 (on)
  using_dma    =  1 (on)
  keepsettings =  0 (off)
  HDIO_GET_NOWERR failed: Invalid argument
  readonly     =  1 (on)
