Just a small note here, differences between FAT and exFAT:

1) Contiguous files get a special treatment by exFAT: they do not use the FAT 
cluster chain.
2) exFAT doesn't use the FAT to track free space, it uses a bitmap.

So, 2 FAT tables are probably not sufficient for recovery, 2 bitmaps are needed 
too.[1]
Btw, only Windows CE supported this.
