So this morning i decided to write a game to my sky3ds microsd, and somehow it has decided to write protect it. I can READ from it fine (or so it appears from the backup i did with diskwriter) but can't write to it at all, that includes moving games from the bottom reserve to the top. Was working fine a couple of days ago when i moved Person Q from the reserve to the top so i could start playing it. Anyone got any ideas or had this happen before? I've tried everything i can think of to just wipe it out totally and start fresh but no luck, still write protected. No, it's not fake card, already confirmed it's a real sandisk extreme pro 16gb.
