This is an area I have been researching for quite a while now. I am down to 2 thoughts about what is happening. I am almost convinced its a hardware issue. Either its the SD card integrity or its the power supply. The reason I point at the SD card as one potential problem is obviously its the source of the problem. I have did hundreds of reloads to test the integrity of the SD and while it will take some rewriting hit over time they hold up fairly well depending on brand. I had the best luck with sandisk cards. (they do eventually corrupt from extensive use I have found) The next problem I kept running into was when I would mount the Pi next to the power supply (within perhaps 2 inches or so?) It kept corrupting the disk every time. The best I can figure is 2 things. Perhaps the EMFs are messing with the SD cards or that the power "supply" was winding up slowly and that might cause corruption? What I mean by that is, lets say that the Pi is plugged in, the power from certain 5vdc sources may be tied to the main power supply of perhaps 12vdc lets say. In some cases you can sponge off the control board that will perhaps have an onboard 5vdc power out. Or a 12vdc to 5vdc power converter? In these instances the power may come on slowly depending on how its bridge rectified and caps and such? So you might not get 5vdc instantly? May perhaps take a half second or less. But that may be enough of a hit for the SD card? This is all considering the 5vdc source is already plugged in to begin?
I have not pin pointed the exact problem but its narrowed down to one of these I think...
I could be wrong but that's what I have seen thus far.
