You should use same algorithm which is used for FAT32. Primary FAT is
first. And all operations are done on Secondary FAT and then is
Secondary FAT copied to Primary. This is backward compatible with
systems which operates only with first primary FAT. And other systems
which see both FATs can benefit from redundancy/recovery.
