I have a WD 500GB external hard drive. It was working normally a couple days ago. I was using it minutes before it stopped working. It was working on one computer and then when I plugged it into another computer I got nothing. Now when I plug it into any computer it shows up as being plugged in, but not under "My Computer". When I go to disk manager it says the drive must be formatted.
I tried running a trial version of another recovery software WD recommended, but got an error, including one about mismatched geometry. That is when I found TestDisk. I downloaded it and ran it, but my external drive doesn't appear, only my internal drive. I wanted to see if I could try and fix the geometry. Anyone know why it might not be showing up in TestDisk?
