Assuming it simply means I have a bad block, what's the easiest way to
force a reassignment of the block? The OS is 3.4-RELEASE.

This assumes you've got automatic bad block reallocation
turned on (modepage 1).
Another option is to reformat it, but IMHO camcontrol didn't provide a
»canned« option for this in FreeBSD 3.4. You could manually do it
with
camcontrol cmd -n da -u 3 -t 7200 -c '4 0 0 0 0 0'
(Careful, there are no seat belts with this command -- if you get it
wrong, in particular that -u 3, you might format another drive without
any further questions being asked!)

Never trust an operating system you don't have sources for. ;-)

Look for AWRE and ARRE in the mode page.

camcontrol format also works for recent FreeBSD versions. man camcontrol
is really recommended reading here.

camcontrol format will ask and is therefore prefered.

(camcontrol format is available only starting with FreeBSD 4.1.)
