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.
