Yes, there is a possibility on why its not working.
Its a 2.5" HDD with power over USB correct?
Well if yours is anything like mine, then it requires a short lead, and alot of power. If you have a cheap chasis, the front usb ports ussually suck, and dont get enough power into the HDD for it to properly spin up, then you get some error messeages one screen.
So do this
1. Find the shortest USB lead you can get.
2. Plug it in the BACK of the computer not the front.
Hopefully that's all whats wrong.... if its not that... then your case has carked it
