Fortunately (or unfortunately depending on how one looks at it), mine
appears to be just bad sectors developing on one of the  "newest"
drive I added to the machine as part of a mdadm RAID 1 array.

After I rebooted the server and after some period of non-activity
apart from the raid resync, I came back to see the console scrolling
with error messages and an email warning in my inbox that a device has
failed.

smartctl quick test aborted with a read error but WD's diag reports no
problem on a quick test so I'm putting it through the full media scan
to be sure.

Hopefully it is indeed just bad sectors but I'm skeptical at this
point because in the original situation, there was no warning email
from mdadm and there was nothing logged when I checked.
