Problems mounting a FreeBSD UFS partitioned hard drive

[wrkr1]

I followed these instructions:

http://askubuntu.com/questions/85154...ufs-filesystem

But the hard drive is still inaccessible even when it is mounted in read mode.

I'm hoping to copy more data to the hard drive.

So what are you having problems with? Post errors you are getting or why exactly it is not working.

I'm sorry I did not include details.

There is a 2TB UFS-formated hard drive in a modular non-RAID external USB enclosure.

I get this popup error when I plug the drive in and Ubuntu tries to automount:

 Unable to access “2.0 TB Volume”

Error mounting /dev/sdd1 at /media/a4090/disk: Command-line `mount -t "ufs" -o "uhelper=udisks2,nodev,nosuid" "/dev/sdd1" "/media/a4090/disk"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sdd1,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

At this point I enter commands to mount UFS manually (using this as a reference http://askubuntu.com/questions/85154...ufs-filesystem )
This is the output from the CLI:

a4090@x785:~$ sudo modprobe ufs
[sudo] password for aaa: 
a4090@x785:~$ mkdir ~/ufs_mount
a4090@x785:~$ sudo mount -r -t ufs -o ufstype=ufs2 /dev/sdd1 /home/aaa/ufs_mount
a4090@x785:~$

After these manipulations I go to the file manager that now sees the volume in question as mounted, but when I click on it I get the following popup error:

 This location could not be displayed.

You do not have the permissions necessary to view the contents of “ufs_mount”.

In the file manager, when I navigate to /home/aaa/ufs_mount (with a mouse, of course) I am able to open the folder with no errors, but there are no visible files within it.
