It is fairly simple, plug it in to usb, then power and it shows up in your drives. I do have to denote one star, as if you're using this for older hard drives instead of ssd's. It starts spinning the disc as soon as you plug the power cable in. So you have to be very careful not to move the hard drive once it's powered up. Or else you can very easily scratch the discs and make that drive unusable. Other than that does what it says!
