The implementation is an ugly hack.

If both total logical sectors entries at offset 0x020 and 0x013 are 0 on volumes using a FAT32 EBPB with signature 0x29, volumes with more than 4,294,967,295 (232-1) sectors (f.e. https://en.wikipedia.org/wiki/File_Allocation_Table

In much the same way, sub-directories are implemented as special files containing the directory entries of their respective files. Ntfs File System Further, the term "VFAT" has led to various misconceptions as well,[nb 1] as it is sometimes erroneously used as if it would describe another variant of FAT file system to be These so-called logical sectors were larger (up to 8192bytes) than the physical sector size (still typically 512bytes) as expected by the ROM-BIOS INT 13H or the disk drive hardware. https://en.wikipedia.org/wiki/FAT_file_attributes Cluster addresses were increased to 16-bit, allowing for up to 65,524clusters per volume, and consequently much greater file system sizes, at least in theory.
In addition to this, the disk driver was expanded to cope with more than 65535sectors as well. File Allocation Table Tutorial Therefore, operating systems should first inspect a volume's optional shutdown status bitflags residing in the FAT entry of cluster 1 or the FAT32 EBPB at offset 0x041 and ignore the data It is loosely based on the File Allocation Table architecture, but incompatible, proprietary and protected by patents. exFAT is intended for use on flash drives (such as SDXC and Memory Stick Subdirectories start with entries for .

Note On volumes with fewer than 32,680 sectors, the cluster sizes can be up to 8 sectors per cluster. Uses The FAT file system has a long history (over three decades) of usage on desktops and portable computers, and it is frequently used in embedded solutions. File Allocation Table Example

In the EFI FAT32 specification Microsoft specifically grants a number of rights, which many readers have interpreted as permitting operating system vendors to implement FAT. Non-Microsoft patents affecting FAT include: U.S. The implementation of a single-sided 315 KB FAT12 format used in MS-DOS for the Apricot PC and F1e had a different boot sector layout, to accommodate that computer's non-IBM compatible BIOS. have a peek here The Windows NT family and some alternative DOS versions such as PTS-DOS fully support 64 KB clusters.
The first incarnation of FAT was known as FAT12, which supported a maximum partition size of 8MB. Fat File System Structure By default, Windows 2000 supports long file names on FAT volumes. Microsoft.[permanent dead link] ^ Garrett, Matthew (January 19, 2012). "EFI and Linux: the future is here, and it's awful".
In 1988, the FAT16B improvement became more generally available through DRDOS3.31, PCDOS4.0, OS/21.1, and MS-DOS4.0.
Reportedly, MIDAS was also prepared to support 10-bit, 12-bit and 16-bit FAT variants. In each case, the file allocation table entry points to the first cluster of the file. March 12, 2002. Fat File System Max Size Specific threshold values for the amount of clusters (as stored in the BPB) have been defined to determine which FAT type is used.

The use of this is largely historical, and it is nearly always set to 0; thus it can be ignored. 0x20 4 bytes Total number of blocks in the entire disk FAT12 was used by several manufacturers with different physical formats, but a typical floppy disk at the time was 5.25-inch (130mm), single-sided, 40tracks, with 8sectors per track, resulting in a capacity
The FAT standard has also been expanded in other ways while generally preserving backward compatibility with existing software. Therefore, even if default issues of MS-DOS and PCDOS were not able to cope with them, most of these vendor-specific FAT12 and FAT16 variants can be mounted by more flexible file Sign in to make your opinion count. Official documentation recommends to trust these values only if the logical sectors entry at offset 0x013 is zero.
