help mount an UnixFileSystem created with osX

[briner]

hi,
I'd like to mount an ufs partition which was created with osX.


        /sbin/pdisk /dev/hda
        Edit /dev/hda -
        Command (? for help): p
        
        Partition map (with 512 byte blocks) on '/dev/hda'
         #:                type name       length   base     ( size )
         1: Apple_partition_map Apple          63 @ 1
         2:     Apple_Bootstrap untitled    31456 @ 64       ( 15.4M)
         3:           Apple_HFS "osx"     5242880 @ 31520    (  2.5G)
         4:     Apple_UNIX_SVR2 swap      1048577 @ 5274400  (512.0M)
---->    5:           Apple_UFS data     26455640 @ 12614432 ( 12.6G)
         6:     Apple_UNIX_SVR2 untitled  6291455 @ 6322977  (  3.0G)
         7:          Apple_Free Extra           8 @ 39070072


So i try the following command:
mount -t ufs -o ufstype=44bsd /dev/hda5 /data
and I get:
mount: wrong fs type, bad option, bad superblock on /dev/hda5,
       or too many mounted file systems

I thought that I should insert the option ufstype=44bsd because the
darwin is based on freebsd

I have no idea how to make it work

Any hints will be really appreciated 

Thanks in advance
