Thanks for all that information Tsuyoshi.
I have turned off dma for this drive with:
[root@karsites hde]# hdparm -d0 /dev/hde
/dev/hde:
setting using_dma to 0 (off)
using_dma = 0 (off)
[root@karsites hde]# hdparm -d /dev/hde
/dev/hde:
using_dma = 0 (off)
I'll watch and see how things go now.
Kind Regards,
Keith
