Every time I try and perform a NAND dump of my Wii U it makes it to one of the later parts of the backup and fails, restarting my WII U and leaving me with multiple files on my SD card, one of which is corrupted. I don't recall the specific error but I've tried it on two different SD cards, both formatted to FAT32 but I end up with a corrupted file on my SD card every time I try this.
Any ideas?
