1. As usual, open up a terminal and login as root: $sudo bash
2. To check which location is the UFS drive name, enter 'fdisk -l'. You should see a line such as /dev/sdc1. Note this down.
@ As an alternative, go to System Administration -> Partition Editor to find out the drive name.
3. Enter mount -t ufs -r -o ufstype=ufs2 /dev/sdc1 /media/freebsd to mount the slice as partition under Linux.
* You can just create a new folder under /media or /mnt, in this case, freebsd.
