Explore FreeBSD filesystem under Windows?

[P.B.S.]

ffsdrv seems to be able to mount only the first slice.
I couldn't get it mount any other slice after playing with it for some time.


# df -h
Filesystem     Size    Used   Avail Capacity  Mounted on
/dev/ad4s1a    496M    124M    332M    27%    /
devfs          1.0K    1.0K      0B   100%    /dev
/dev/ad4s1e    248M    110K    228M     0%    /tmp
/dev/ad4s1f     18G     14G    2.6G    84%    /usr
/dev/ad4s1d    248M     63M    165M    27%    /var
/dev/ad4s3      42G     29G     13G    69%    /mnt/c
/dev/ad4s5     172G    161G     12G    93%    /mnt/d

Mounts /dev/ad4s1a only. I need /usr/home/.... (ad4s1f).
Any ideas?
