My neighbor came over with a big problem. On a vacation he managed to wipe his PC clean, and the biggest problem was the dissapearence of the tons of photos from the trip.
I knew I had used a program previously to recover one of my own hard drives, that had the accident to suffer the same fate. But I was not able to remember what the program was called.
Searching for the phrase "harddisk recovery linux", gave a lot of results, but I had no clue of what to click.
After a while I found "TestDisk" which is the best I have ever come across.
I remember the last time I used it I donated around 20USD because I was so happy.
