Basically, B appears to be "write-only"; it will never return an error on a
write, but just try to read from it, and you will be sorry.
It would be interesting to see what SMART says about drive B, especially
the short and long self tests.

On my hard drives, automatic online testing is turned on, and so is
automatic offline testing. I run the long self-test once a week.
I have two drives which can play the role of B. One of them has this
SMART output:
[root@cmccabe-devel root]# smartctl -d ata /dev/sdb -H

=== START OF READ SMART DATA SECTION ===
SMART overall-health self-assessment test result: FAILED!
Drive failure expected in less than 24 hours. SAVE ALL DATA.

The other one passes SMART.
Both of them eat data, though.
