I have an SD card that apparently is formatted exfat. I tried copying some music onto it, and now my CM/marshmallow phone is saying that the card is corrupted. It mounts on my linux system, and running fsck gives me some file errors. But I can't fix them. I have no access to windows (well, maybe my wife's fairly locked down work computer). I'm leaving on a trip tomorrow and don't have time to pull off, reformat through android, and then reload my files. Any ideas?
