The first error is data transmitting error. Your HARD DRIVE have a data transmitting error or malfunction on transmitting path without disk. (The trouble is on memory, chip set, IDE-cable, HDD-Circuit(DMA). HDD dish is OK.) DMA I/O was designed with 2 separated unit (control-unit and data-unit) The trouble is on control-unit part.
Vivard/smartctl only explains your data-unit is OK.

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
