I had my computer and external hard drive set up in one place. I packed it all up, put it in my car, and moved to my new place. It was in the car for about 8 hours in a box along with other stuff like wires and my keyboard. The hard drive did not experience a rough ride, extreme temperatures, nothing like that.
Anyways, I set up my computer, but accidently used a 19V, 2.1A adapter to power the external hard drive. I really doubt this would cause my hard drive to break, but it is not working now. When I plug it into the power, the drive is clearly making 0 noise. Thus, it does not show up on my computer, nor does it show up in Drive Management on Windows 7.
Is my drive broken?
Edit: I have tried different USB drive, different USB port, different computer. Neither the 19V adapter which I accidently used, nor the 12V, 1.5A adapter that I’m supposed to use power up the drive at all.
