Ken from Redondo Beach, CA
NewerTek Universal Drive Adapter

Ken is a photographer and has a 5TB external drive that isn't seen by his computer. Leo suspects that the external drive enclosure is the problem. Before you replace it, get the NewerTek Universal Drive Adapter and see if you can connect it and see it. If you do, then you know it's a bad enclosure. If you can't, then you know it's a failing hard drive.
