Thank you so much (and other email too).
I did a grep -a over my filesystem for a few entries I would see in my
disklabel. It found source code, docs, examples. But after several hours
it found four identical copies of my disklabel (from /var/backups). I
used "disklabel -R sd4 J.disklabel-NEW" and was able to mount my
partitions. Doing a find over them caused both of the mount points to
fail. (I didn't handle the bad blocks.) I rebooted, replugged in the
disk caddy, and re-mounted and was able to copy over my missing files.
(Note to self: 1) make sure my backups are complete for what I need; 2)
don't ignore disk errors; 3) monitor disk for SMART and disk errors.)
