a) FAT a FAT16 jedno a totéž jsou

ani náhodou,

b) ve FAT16 vytvoříš disk o max. velikosti 2GB

nie je pravda

The 4-GB partition limit is imposed by the maximum number of clusters and the largest cluster size supported by the FAT file system. In Windows XP, FAT16 is limited to 64K clusters. Multiply the maximum number of clusters (64k) by the maximum cluster size (64K), and the result is 4GB. In addition to Windows XP, Microsoft Windows 2000 and Microsoft Windows NT 4.0 also support FAT16 volumes up to 4GB in size.

FAT16 volumes larger than 2GB are not accessible from computers running Microsoft Windows Millennium Edition (Me), Windows 98, Windows 95, or MS-DOS. The size limit for FAT16 volumes in these operating systems is 2 GB. In other words, to maintain compatibility with Windows Me, Windows 98, Windows 95, or MS-DOS, a volume cannot be larger than 2 GB.
