How To Recover FAT Partitions

Remember that a FAT directory is just a special file entry; it exists on a FAT file system as a file entry but in terms of recovery exists just as a file.
You can recover a deleted FAT partition by finding the first sector of the partition and using your forensic tools to reconstruct it. For a FAT partition, the first sector, or the volume boot sector, of the file system will begin with ëX MSDOS or ëR MSWIN4.1 and end with hex characters 55 AA. For FAT32, a backup of the volume boot sector also is
present, so if the volume boot sector is overwritten or physically damaged you can still recover the partition.
