Well I was walking to my car from school, I dropped the hard drive about 2-3ft. It had a little scuff on it, I didnt think anything of it, When I get home to plug it in, it doesnt show up on my desktop. I opened the disk utility and it shows 2TB drive. Whenever I try to erase or partition it gives me an input/output error. Is this drive gone for good? Also, the drive lights up and I can hear the disk spin.
