msdosfs and FAT16

[Benjamin von Mossner]

Hi list,

i have a problem mounting my mp3player, attached via umass on
FreeBSD 5.2.1. It is recogniced correctly (from my point of view).

# uname -a
FreeBSD bensons.bejuwg.intern 5.2.1-RELEASE-p3 FreeBSD 5.2.1-RELEASE-p3 #0: Wed Mar 24 02:01:10 CET 2004 benny at bensons.bejuwg.intern:/usr/src/sys/i386/compile/BENSONS i386

option MSDOSFS is compiled into kernel

# grep -c MSDOSFS /usr/src/sys/i386/conf/BENSONS
1
# kldload msdosfs
kldload: can't load msdosfs: File exists

Now when i try mounting, i recieve the following error.
# mount -t msdosfs /dev/da0s1 /mnt/mass
msdosfs: /dev/da0s1: Invalid argument
#

Even better a 
# dd if=/dev/da0s1 of=temp count=1
1+0 records in
1+0 records out
512 bytes transferred in 0.005233 secs (97844 bytes/sec)
# strings temp
FAT16
#

The device is found by fdisk, i "could" do a newfs for sure and
furthermore i can mount it under Solaris 9, OSX and Billy-OS but
not FreeBSD 5.2.1....

Help would be greatly appreciated :)

Cheers
benny
