Seems to have a problem with DMA
[root@debian-f5ibh] ~ # hdparm -iv /dev/hda2
/dev/hda2:
multcount = 1 (on)
IO_support = 1 (32-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 3649/255/63, sectors = 29302560, start = 9767520
HDIO_GET_IDENTITY failed: Invalid argument
[root@debian-f5ibh] ~ # hdparm -d1 /dev/hda2
/dev/hda2:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Invalid argument
using_dma = 0 (off)
