Thanks so much for your response.
I'm not that techy, so I'll try get a friend to help. I understand some of what you're saying but this sort of stuff isn't my expertise at all. :/
When I got home from picking up the HD, I put it into a dock and realized that they wiped everything off of it by initializing it. Now, I have an "Untitled" drive with nothing in it.
When this problem first came up (before taking the HD to them), I put it into the same dock I mentioned above, and ran a scan with Disk Drill. The scan revealed that there was over 300GB of files on the HD, but I didn't have the software, an extra HD, or know-how to restore the files. Each time I plugged in the HD to the dock, it asked if I wanted to "Initialize" it and I never did.
All I have now is the HD with no case. The parts are all separate. I can try to get a friend to help with your suggestions, but now that the HD has been wiped, I'm not sure what the next course of action should be... :(
Thanks for this tutorial. My name is Cherisse and I'm currently in this situation and feel extremely defeated. My friend followed your recovery steps to help me fix my HD, however, he said that it seemed like two of the contacts on the USB connector had broken off and he couldn't continue with the steps. I took it to a computer repair shop and after waiting a week, they told me that they can't find a single file on it. I find that strange since the hard drive itself is not damaged. I don't know what to do and would love your help. Is there a way I can email you to get additional help and advice? I would really appreciate it. firstname.lastname@example.org
