So. I have an M3i zero. It stopped working suddenly, saying a file was corrupt, and to reformat the disk. so, I popped the flash card reader into the computer, copied my files to another folder(downloaded a new copy of Sakura too, and I think I might need new software for the actual m3i?), and reformatted. It finished, and I went to copy my files to the M3izero drive. It wasn't there. Instead there was just a drive labeled "J". I tried opening it, but it says there is no disk. I tried reformatting, but of course, it's not reading the disk, so can't do that. I tried restarting, and of course that didn't work. This m3i, card reader and card are just about a year old. What can be wrong? How can I fix this? or do I have to buy a new flash card reader and disk? (How do I do that without having to buy the whole package, anyway?)
