I am testing some new 8TB disks. I've taken to doing
dd if=/dev/zero of=/dev/rsd3c bs=64k
and
dd if=/dev/rsd3c of=/dev/null bs=64k
as a first test. It's depressing how often I've found problems
on big disks. Today, the read test produced an error in the messages
file I've not seen before:
Jun 28 16:17:39 paladin /bsd: sd3(umass0:1:0): Check Condition (error
0x70) on opcode 0x28
Jun 28 16:17:39 paladin /bsd: SENSE KEY: Aborted Command
Jun 28 16:17:39 paladin /bsd: ASC/ASCQ: Information Unit iuCRC
Error Detected
So it isn't a soft read error -- what is it? It might be useful to
indicate where the error occurred? This is the second of three
disks to be tested. It's connected to a Thermaltake USB 3.0
disk enclosure.
Thanks for any pointers.
