Try for identification:


	# file - < /dev/da0

and

	# file - < /dev/da0s1

and post the output of the two commands.

Make sure you're accessing the correct device file, i.e. when a
slice ("DOS primary partition") has been established, use da0s1,
if not, da0 - it depends on how the file system is "embedded".
