Strange. This is a scsi drive, so I don't believe hdparm works with
scsi.
Is there something similar with scsi drives? I though DMA was an ide
thing,
but I'm probable wrong.

Ok, first, if I told you I've used three different drives and got
the same error, how would it matter what the current hd specs are?
kernel is a stock 2.0.35 kernel from rh 5.1.
I'm assuming this error MEANS something and isn't reliant on
a specific manufacturer, but to satisfy everyone who may be
asking the same questions:
brand is a 6.4gig Quantum Fireball SE.
The interface is scsi, but it's happened on many ide drives as well.
The other drives were Quantums as well. If there is a problem with
quantum drives and linux, that would be swell, but I need to know.
Thanks

I didn't realize this was a SCSI drive. In that case, your most likely
problem is bad cabling or bad termination. Try using a different cable,
and active termination.
