Since I bought my M3Perfect in late February, I've gone through 2 2GB microSD cards with it. The first one (a genuine Japanese Kingston from ozmodchips) was corrupted within a couple of hours of first using it, and the other (a generic that I borrowed from my housemate) died just now. Could it be the cheap USB adapter that I've been using? Have others had problems with their SD cards, or is it perhaps just an M3-centric problem? Also, I've yet to return the Kingston card to ozmodchips due to a sudden death in my immediate family just after I purchased the products. I've had far too much on my plate recently to be faffing around with my DS until now ._.
