I attempted Alan's suggestion and dd'd to the tape. /dev/md0 is > 130G and dd borked almost immediately:
root@scriptor:/home/manager dd if=/dev/md0 of=/dev/st0 dd: writing to ‘/dev/st0’: Input/output error 3+0 records in 2+0 records out 1024 bytes (1.0 kB) copied, 15.2882 s, 0.1 kB/s Funny thing is that the Superloader passes all of its internal diagnostics as far as I can tell. Suggestions on how to verify which piece of hardware is causing the problem would be greatly appreciated.
