Ever since I installed bootmii and made a back up a few months ago I have never been able to move the nand.bin from my sd to my computer. I've tried this on both Windows and Linux. I get an I/O error(input/output) when trying to move it. But...everything thing else on my sd is able to copy to the computer. So today I backed up everything else on my sd, then formatted it. Then dragged all the content back onto the sd, put it into the wii, then made another nand backup. Hoping this would solve the problem. But it didn't. When I try to move the nand.bin to my computer again, I get the same I/O error. Anyone else ever come across this? And if so, what did you do to fix it? Thanks.
