Hi, I got a m3 perfect adapter with a micro-sd card (2gb, sandisk). I was very happy with it till yesterday. When I was to insert the card into my reader to fill the card up with some more games/music/videos windows kept complaining about it being write protected. Now, I havn't touched the write protection lock on the micro-mini-sd adapter and I sure as hell havn't set the files to being write protected either. So I'm wondering what's causing this and how to solve it? If anyone even have bumped into this problem before... I've tried googling without any luck, most hits I get is about phones locking them down, no result are directly connected to ds/m3 or so. EDIT: Errr.. nvm, solved with a piece of scotch tape over the mechanical lock on the micro/mini-sd adapter. The problem lies in the reader, not the card or the ds.
