fsck can't determine fstype

[Robert Huff]

       Situation:
       I have a hard drive which may or may not have died already,
from which I would _very_ much like to recover maybe 1 gbyte of data.
       After extracting it from the old machine, it's now hooked up to
a system running:

FreeBSD 10.0-CURRENT #0: Sun Dec 30 12:52:09 EST 2012 amd64 

      "gpart show" identifies it as "ad1" with partition 2 as type
"freebsd-ufs" and label "g_user".
	  However:

>> fsck /dev/ad1p2
fsck: could not determine filesystem type

      Adding " -t ufs " produces:

huff@>> fsck -t ufs /ad1p2
** /dev/ad1p2
** Last Mounted on /usr
** Phase 1 - Check Blocks and Sizes

      While I'm not an fs expert, this feels wrong.
      Is there some clue I'm missing?

      Respectfully,
