I see a lot of these errors:

Is there any way to detect what exactly is causing this? To the best of
my knowledge, the disk works fine - even my raid1 set on this disk isn't
impacted, the speed stays ok, I'm wondering if there's a command being
sent the disk (or the controller) doesn't know how to handle.

smartctl isn't active, BTW.

Thanks,

There was corruption on the cable between the controller and drive. That
usually indicates a cable or noise problem in the PC but could indicate
mistuning of the interface. Make sure the IDE cable is 


 [controller]<---- long section ----->[slave]--short section-->[master]


as one common cause is having the cable the other way around.

The cable happens to run the correct way, but you've given me a valuable
hint. I was wondering why hda had errors and hdc (which is the same
drive on the second port of the controller) didn't. Perhaps I'll try
another cable.

Thanks,

You could only have one person in the car at a time, unless you
bought "Car95" or "CarNT". But, then you would have to buy more
seats.

Another common cause is to have the master and slave swapped. The
master should be at the end of the cable.
