Recently, a friend of mine used my external drive and managed to drop it. I plugged it into my pc and it worked fine. I downloaded files from it like normal. When plugged into my pc the second time, some odd things happen. To begin with, my computer recognizes the drive and shows it in the "this PC" tab. Secondly disk manager shows the drive, but says it is 100% empty when i know it isn't. When my computer mounts the drive and loads it, it says it needs to be formatted. It does this as well if i try to open it.
