Even if you did get it from a legitimate store, it could still just be a bad card. Take it back and get a different one and see if you have the same problem.
Ok I got another SD card and that doesn't tell me SD card found after a restart....so this seems to be better but in Xbox music, most of the files are unplayable and give me the error code 80070002. The after a while mg musics start vanishing with the used up space being the same. Why is this happening to me? What's the problem cuz it happens on the old bad card and the new one as well.
