Ok, so I have a Toshiba Canvio connect external backup drive. Until last night, it was working properly. Now there is absolutely no power going to it (the led does not light up). I'm not sure if it got jolted a bit in my bag or what, but I know how to take it apart. I want to test to see if the hard drive is damaged, but have no external connectors for it. What would happen if I put the external into my laptop without an os? Could I test it that way?
