So I loaded my 3DS XL up earlier, booted into gateway mode, pressed select, about to enjoy some Phoenix wright, all of a sudden It says 'read error' I think hmm okay, try it again. Same problem. Put it into an adaptor, the laptop won't even recognise the card has been inserted. Put the normal SD card into the laptop, works fine. I tested the MicroSD as soon as I received It and It's definitely genuine. I'm just about to order a replacement on Amazon but I figured before I do I'd ask you guys and see if you have any Ideas what's gone wrong somewhere or any Ideas on how I can get the laptop to read the card. Thanks.
