And here you can see the correct identification for the
Linux partition (compared to the initial example).

I'd suggest you use the Linux native fsck (e2fsck). If I
remember correctly, there is also an "ext2 fsck" in the
port e2fsprogs with the same name.

Or maybe it came with FUSE?

Basically, you'd so something like

	# fsck -t ext2 /dev/da1

or, as I mentioned,

	# e2fsck /dev/da1

An automatic file system type detection relies on an entry
in /etc/fstab, which you don't have, so you need to specify
the FS type manually.
