It's a Wondershare Miracle!
I had lost a number of photos and videos that were corrupted on a camera disk. I tried four other programs to no avail. Spent a lot of money, and then I found Recoverit! I think it recovered every photo and video that was ever taken in 13 years! There was a lot of confusion determining which version to buy and what to do to recover. It cost a bit much, but it was worth it. Recoverit found my photos and videos.
