I was in the same boat as you a few months ago. My computer's hard drive crashed and I lost all my data. I was so devastated that I didn't know what to do. But then, I found this
Partition Recovery™ software | DiskInternals program that helped me get my data back. It automatically scans your disk for lost or damaged files and helps to recover them. If you're anything like me, you'll be glad you have it!
