Yes, that is a failing disk. I don't know why the PERCs don't fail them
when this starts to happen, but the disk is clearly reporting that it
has had 13 uncorrected write errors. That may be okay for Dell's data,
but not for mine.

Usually in this case I start a long self-test on the disk in question
(as well as on a spare so I have a reliable replacement). Often the
self-test will fail sufficiently to get Dell to replace the disk, or it
may even force the PERC to fail the disk.
