I have twice experienced a disastrous behaviour on my Pi: My Samba share had all the files wiped out. It was around 600 GB of music files. The rest of the files on the hard disc was intact, this affected only the music folder, which I had set up as a Samba share on my Pi. The hard disc itself is attached to my router. In addition to these files, I had also lost the server and player programs/folders on the Pi. Everything in my /home/pi folder was erased, while the rest was there.
I have experienced SD card corruption before, but this is not it. So I wonder if anyone has experienced something similar. Has a prankster hacked my system, or has my programs self-destructed and wiped out everything in my /home/pi folder itself?
