Hi there - I'm thinking about adding a 2nd hard drive to my Aurora R8.  I've heard there's a limit of 2 TB per drive - which is fine.  However, I'm uncertain if the wires I need are already in the box.  I've been inside to upgrade memory and I see some additional unconnected wires in there and I'm not sure if those are what I need or if there's something else.  Anyone do this before that could lend some guidance?  Thanks!
