For the latest drivers, when we detect a Quantum 160MByte/s drive we
automatically reduce the speed down to 80 in order to get around an issue that
causes SCSI bus lockups and resets. It should be fixed in the future, but in
the meantime the 80 is intentional and is a work around for a worse problem.
