My guess is that you killed the power supply or interface module in the hard drive enclosure, so you probably just need to figure out how to get the drive out of the enclosure (not easy on some of them), and plug the hard drive itself into a desktop computer and you should be fine.

But that might be a bit ambitious for someone without the necessary experience to tackle as a first project! Do you know any highly computer savvy people where you live that might help you?
