WTF!
Okay get this. The 2 WD HDDs where in my PC case. At this time these drives did not work and the external ones that I hadn't mounted as I was just testing did work.
I've now switched these drives around as I thought the old drives where working and the new ones where not. AND GUESS WHAT!
The new ones not work outside the case and the old ones in the case no longer work! I ask you, WTF! LOL
Somehow the case much be messing up the drives but i have zero idea as to how.
