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. -- -Chuck
