  FAT32 reserves 1st 32 sectors for boot record.
    3 sector boot record at logical sector 0 and backup at 6 

  Following the boot sectors are 2 copies of the FAT.

  FAT 32 creates 2 copies of the partition volume boot record.

  OS can toggle between copies to find a good copy.

  FAT 32 treats root directory as a standard directory, 
    up to limit 65534 entries like all other directories.

  Although FAT 32 capable of 8.8TB, field size in MBR limits it to 2 TiB.

  Large Partition (8GB) with small clusters (4KB)
    64 MB FAT - Since FAT used a lot, tends to be cached.

  Largest problem with FAT 32 is its limited or  non-existent support 
  by older (Win95) or different OSes (NT, Mac)    

  Emergency boot record must be created by Win 95B, 98, ME, 2000, or XP.

  Still no security, encryption, or compression.
