I wanted to back up my SD card to my PC, then format the SD with 64k clusters (it currently has 32k), then copy all the files back. However, when I try to copy all the files over nothing happens. So I tried copying individual files and folders and it worked on all but 2 folders, the retroarch and "nintendo 3ds" folders. They seem to be behaving strangely. When I examine the properties of these folders, I get these results: http://imgur.com/a/hvki3 http://imgur.com/a/RmNMA http://imgur.com/a/t1X6M Both folders claim to be well over 25GB in size, and there are wierd files in the retroarch folder. The 3DS boots fine and everything runs fine. Even windows and godmode9 say that only half the space on the 32GB SD card is used. I just can't copy the nintendo 3ds and retroarch folders to my PC. I also looked at directory info for those folders in godmode9, and it says "Analyse dir: failed!"
