Yesterday, when I came back from work, my Pi was dead. Only the red light is on. If I try to restart it, the green light will flicker for only a short while, and there is no reaction on the other two lights.
I have experienced that an SD card has become corrupted before. But I tried several of them that I know would work, including a new one that I just flashed. So that is not the reason. And I haven't overclocked the Pi.
The Pi has been running stable since I bought it. It is the original model B with 256 MB RAM from May 2012.
I recently had a possible hacker attack. Everything in my home/pi folder was erased, including the Samba share on my NAS with 600 GB of music files. After that I moved the server to another computer and kept only the music player, while I also changed passwords. But could a hacker possibly be able to destroy the hardware? Or did it happen because the Pi was about to die?
