so I bought a 128gb from geek and used it with the 3ds guide and a N3DS. Everything was working fine and I got a few titles and it must have reached the point of the cards true capacity. Even though my card still says 117 gb still available. I have installed boot9strap and updated to 11.4 and I've noticed if I take the sd card out the system won't start. I've tried to drop and drag contents to a new sd card and that don't work either to make it start again. If I put the bad card in it will boot. so my question is how can I turn on my 3ds without a sd card in and is the sd card now my OS. And how can I transfer bad sd card to a good sd card?
