 The first data cluster is 2, and consequently the last cluster codice_33 gets number codice_35.This results in data cluster numbers 2...4085 (0xFF5) for FAT12, 2...65525 (0xFFF5) for FAT16, and 2...268435445 (0x0FFFFFF5) for FAT32.The only available values reserved for future standardization are therefore 0xFF6 (FAT12) and 0xFFF6 (FAT16).
