scsi errors on orb drive

[David Bear]

in the search for reliable high density backup media...  I chose to
use orb drives a couple years ago.  2.2 gis on a direct access device
seemed good.  Now that one failed completely and another seems
troublesome, I'm beginning to understand why they are out of business.

below is a kernel message that was thrown when I attempted to umount
the orb drive.  Can anyone tell me what it means?
