fsck on FAT32 filesystem?

[Ronald F. Guilmette]

I have a sizable (200GB) external USB 2.0 interface hard drive.  (Actually,
it's a plain old PATA drive in one of those enclosures that allows it
to speak USB 2.0.)

So anyway, to make this external drive work with things other than just my
FreeBSD system, the drive has been formatted so that it contains a single,
all-encompassing FAT32 filesystem.

For various reasons that I won't go into, the thing experienced a power
fail while it was being written to.  I can successfully remount it on
my FreeBSD system, so apparently, the FAT32 filesystem isn't too awfully
damaged... at least not in the vicinity of the root directory.  But I am
old school, and paranoid, so I'd really like to run the FAT32 equivalent
of fsck on the thing, to clean up any filesystem glitches.

Is there any such a tool (as fsck for FAT32) available for freeBSD?  If so,
where would I find it?
