I would suggest you boot single-user and run
mdmfs -s 1m md /tmp
recoverdisk -w /tmp/_.wl /dev/ad4 /dev/ad4
That will find out how many bad sectors you have and try to recover
the contents of them if possible, leave it running as long as you
care for.
If you interrupt it, the /tmp/_.wl file will contain a list of areas
not yet successfully read/written.
