Hmm, adressing is certainly correct or disk access would fall over
on evry and all ATA installation. However if this is semilar to the
problem on the 40G Seagate that we have seen, it might be timing
related.

One place could be to add a DELAY(1) between the OUT's in ata_command
where the parameters are output to the taskfile, maybe we are hitting
the drive too fast for it to get this right...
