So I always had the 2gb default SD card in my 3DS... but it was getting cramped with my photos and Demos... so last night I got myself a 16GB SD and copied all the stuff from the 2GB SD to the 16GB SD... placed it in my 3DS... all was fine, apps were there, photos were there... all perfect. This morning I open up my 3Ds... and now the apps are gone... no swap notes, no netflix, no nintendo video... no game demos I loaded from the eshop... I check the album and all my photos from the SD card are there... reboot... still nothing... I go to the app store, redownloaded Swapnote, now it shows perfectly on the home menu, but all my notes I had in it are gone... I opened kid icarus and it gave me the message that it was creating extra data... I opened Mii plaza, and I was missing all the new puzzles I had and it was about to create extra data as I was to access the FindMii 2... and thats when I got scared 'cuz I'm like at my 3rd walkthrough in that Findmii and I really dont want to restart everything. So I then re-copied everything back on the 2GB SD Card and everything was fine again... Are the SD card signed to the console? So changing SD card means loosing everything?? How can I do the change from the default 2GB without loosing anything? Thanks!
