Install /usr/ports/sysutils/smartmontools and provide output from
"smartctl -a /dev/ad10" (assuming the questionable hard disk is still
installed there); I can help decode the output.

You might also want to run "fsck -f /dev/ad10".  There are known cases
where backgrounded fsck can't fix some errors, but I'm not sure if the
kernel would return errno=6 (Device not configured) to userland in this
situation.
