   the drive is connected to the computer via a cable to the motherboard   
   rear USB 3 port. I think I have good cables, but I wonder if they have   
   adequate shielding, so I'm checking out ones that do. these look good?

   The motherboard is new, and I'm not seeing any issues with transfers   
   to/from with/the internal drives

   how do I tell it to check the USB connected drive?
