External hard drive not discoverable

I’ve added a USB 3TB WD External drive to my new TV Live Hub but can’t get it to appear. Thumb drives show up fine, but not my external drive. I’m stuck running firmware 208.13 because it’s the only version that will support my wireless USB device. After resets and trying different settings options I can’t get my external drive to show. Suggestions?

Not sure, but I think you need at least 2.09.xx for a 3tb drive to be recognized.
