ExFAT?

Most of the larger (32/64GB+) SD cards are preformated with exfat, not
vfat, but you have to use the FUSE exfat file system and utilities on
Linux.  If you reformat the card on Linux using mkfs.vfat, you lose
that.  It's the format my Canon camera uses with 64GB cards, so I've
gotten use to it even though the file size limit isn't important to me.
