BTRFS or EXT4 filesystem for 2TB external drive

Understandable.

I don't think so, but 12.04 is still supported, so if you break it again and we figure out how to fix it you'll be contributing to Ubuntu. :love:

Ok, so I changed my sister's HP Micro server to the latest Ubuntu and thought I would give it a shot again on mine. I installed it alongside the 12.4 LTS release already on there. When I boot into the LTS one the drive works 100%. When I boot into 15.04 then I get that same error again and the drive does not want to mount. I will take a screenshot of the error I get tonight.

I go into the "disks" app and mount from there.

OK, I have a second hard disk formatted ext4 that is mounted automatically by an entry in /etc/fstab.
I am going to comment out the entry in /etc/fstab and see if I can duplicate the problem here.
I am also running 15.04.

Edit: OK, that worked fine.

Let's see what your 'dmesg | tail' tells us, and also please provide the output of:
Code: 
sudo sfdisk -l /dev/sdb
and
Code: 
sudo blkid

And how are you doing that?

After you get that error message, open a terminal, type 'dmesg | tail', press Enter and copy-paste the output here.

Can you go a little further back with the dmesg output please?

Maybe try 'dmesg' without the tail and scroll back until you see any messages different to the above.
I'm trying to see where things start going wrong.
