Thanks for all that information Tsuyoshi.

I have turned off dma for this drive with:

[root at karsites hde]# hdparm -d0 /dev/hde

  setting using_dma to 0 (off)
  using_dma    =  0 (off)

[root at karsites hde]# hdparm -d /dev/hde

  using_dma    =  0 (off)

I'll watch and see how things go now.

Kind Regards,
