Default Mounting/Reading Samsung USB drive

Hi All

Apologies up front for being a FreeBSD/Linux complete novice.... I'm I.T literate, and have a problem accessing a Samsung_S2 USB drive, that for the majority of time is connected to my Panasonic Tx-P42G20B TV, which I know formats this device when you pair the 2 together. It also does state that you will not be able to read it elsewhere..... therein lies my predicament...and challenge! :-)

I can see form the TV's system information/licence details, that it is FreeBSD with the possibility of the disk being UFS2. I have deduced that the USB picks up /dev/da0.. and have tried the following mount commands

mount -t UFS /dev/da0 /mnt/colin (n.b dir colin created with chown 777)
ERROR - Mount: /dev/da0 : Invalid argument

mount -t UFS2 /dev/da0 /mnt/colin
ERROR -

From a (not mine) similar thread ("mount_msdosfs /dev/da0: : Invalid argument"), I have seen replies requesting information output from certain commands, so ahead of any replies here, please see below to the output of those commands. Whilst this thread gave me some decent background, it didn't help me solve "my" problem" and seemed to stop posting last December, which is why I've started this new thread.

Can anyone help in being able to successfully mount the disk and getting at the data, which I believe is on the first partition of the disk (assuming I'm reading the output correctly) ??

Like I say, I'm new to all thgings FreeBSD/Linux, so any detailed help would be very welcome :-)
