Is your harddisk a wide SCSI drive? I've hear of someone who saw something
about as weird when he used a narrow scsi drive on a wide scsi controller.
Apparantly the communication between the two about which bus width (8 or 16)
to use was simply not working. It was not Freebsd, and I forgot about the
details.

So, just wild guess.
