My data on a physical copy corrupted, it wasn't my main town thank god... BUT it was my 2nd town which i do trades with and had ALL my bells from these trades. I used the 2nd town because i didn't want a void villager from the wifi pools when i still only had 9 villagers in my main one. I was in the process of saving and i put my ds on my bed and I got off my bed, when i climbed out, i guess it moved the comforter/blanket and my ds fell to the ground. The cartridge popped out and i tried loading my game and BAM.. CORRUPTED!
However, my main town is a digital copy and I plot resetted like crazy so theres more than 600+ hours in there and never once corrupted.
