I'm assuming that particular sector on the drive is dying, I have
backed everything up on the drive, can anyone give me more
information, should the drive simply be replaced or is it possible
that this is simply a TOC error and could be corrected by newfs to
the drive?
I'm guessing it will need to be replaced, output of smartctl is
below....
You can try doing a "dd if=/dev/ad2 of=/dev/null bs=64k" in order to
read all of the sectors on the disk and get a better feel for how
well it is doing. But it certainly appears that your drive has run
into enough errors that it no longer has spare sectors available to
replace the failing sectors-- you should replace it soon.
