I have a 2 tb toshiba canvio hard drive that I bought a couple of months ago that was working fine. I recently lent it to a friend of mine because he was having issues with his macbook and apple support said he needed some extra space to do whatever it was he needed to do. Well when I got back the hard drive it lights but doesn’t show up anywhere. Not even in disk management. The problem comes that one of my usb ports had a power surge recently and I’m not sure if that is the cause of the issue because its not getting enough power or if the usb port is longer 3.0. I also plugged it in to another laptop and the light turned blue instead of white when i plug it into my computer. But it still didn’t show up. So I;m really confused as to what the issue is and couldn’t find any help. So if anyone has any idea and can help me it would be greatly appreciated.
