deKay,
thank you for your excellent guides.

I am having trouble with using my PNY MicrsoSD XC 64GB card. My system is a New 3DS XL bought earlier this year. I formatted it using my Mac OSX’s “disk utility” program. All the data from my old card copies onto it fine, and the games from my old card are playable with my saved progress intact. The system also shows me as having over 450,000 available blocks.

My problem is that whenever I go to download something from the E-Shop I am being told that I do not have enough space left on my SD card or that it is not compatible. This is the same message I was being told before I upgraded from the factory default 4GB MicroSD card that came with my system. So, since my games and data from my old SD card work I am inclined to believe that the card is formatted correctly. However, why when it shows that I have over 450,000 blocks then can I not download more games for “lack for space.”

I am inclined to think that when I transfer the data from my old card, after it was saved on to the PC, that there might be some way OSX merges the data that is different from Windows, perhaps. This is the only thing that I can think of.

Thank you for any help that you may be able to provide
