Also new disks can fail. If you get this error with other disks also, it is
the controller, but the error message tells about failure of the disk.
Maybe this error results from a bad answer due to a broken controller, but this
is best checked by testing the other SCSI components. If your Seagate is the
only device failing... you know what to do.
