I hope this is the most appropriate place to ask, I'm a bit of a n00b and my frustration levels have peaked, so any help will be greatly appreciated. My problem seems to be just from trying to copy my redNAND from an old SD card to a new bigger SD card.
My end goal is a 3DS where I have most of my games on a 32gb microSD card ready for when I go to Japan in June. I have followed Plailect's n00b friendly guide up to part 4, bullet 23. It was at this point I have realised the 4gb microSD isn't enough to continue with the process, so I'm trying to upgrade from the stock 4gb Toshiba microSD to a 32gb Sandisk I had lieing around (which I would have to do at some point anyway).
My main computer is OS X but I have been using a windows vista laptop as well. On OS X I've tried 'emuNAND Tools' to backup from my old SD card and restore to the new one. On Windows I've tried Hex Workshop to save sectors from the old SD and restore onto the new one. I tried Emunand tool which doesn't detect the SD card and I also tried 'USB Image tool' and 'EaseUS Partition master' to increase the partition. None of it works. The closest I have gotten is with Image Tool which successfully creates a backup and restores succesffully to the new SD(and works in the 3DS at this point), the problem arises when I expand the fat32 partition using EaseUS partition master which leaves the card unreadable.
Any ideas anyone?
