Pi. B, 5. 12 Ti. B recommended. Pi. B (theoretical 1. Ei. B–1). Most of the vendors signing on for licenses of ex. FAT are either for embedded systems or device manufacturers that produce media that will be preformatted with ex. FAT. The entire File Allocation Table (FAT) family, ex.
FAT included, is used for embedded systems because it is lightweight and is better suited for solutions that have low memory and low power requirements, and can be implemented in firmware. FAT allows individual files larger than 4 Gi. B, facilitating long continuous recording of HD video which can exceed the 4 Gi. B limit in less than an hour.

Value Descriptions for Start Entries. Specifies a driver that is loaded (but not started) by firmware calls made by Ntldr.
Current digital cameras using FAT3. Gi. B. With the increase of capacity and the increase of data being transferred, the write operation needs to be made more efficient. SDXC cards, running at UHS- I have a minimum guaranteed write speed of 1. MBps and ex. FAT plays a factor in achieving that throughput through the reduction of the file system overhead in cluster allocation. This is achieved through the introduction of a cluster bitmap and elimination (or reduction) of writes to the FAT table.
A single bit in the directory record indicates that the file is contiguous, telling the ex. FAT driver to ignore the FAT table.
This optimization is analogous to an extent in other file systems, except that it only applies to whole files, as opposed to contiguous parts of files. FAT is also supported in a number of media devices such as modern flat panel TVs. For example, Sandisk ships their 2. GB CF cards as ex.
FAT. Technical specialities. Microsoft asserts that ex. FAT is covered by US Patent 8. Microsoft had also applied for, and so far in some cases, received additional US patents on separate components that are used within ex. FAT. Since Microsoft has not officially released the entire ex. FAT specification, the Name Hash patent application is a key document in providing internal details in the understanding of the file system, since those details were revealed in Appendix A of the application.
File and cluster pre- allocation. For each file, ex. FAT uses two separate 6.
Valid Data Length (VDL) which indicates the real size of the file, and the physical data length. To provide improvement in the allocation of cluster storage for a new file, Microsoft incorporated a method to pre- allocate contiguous clusters and bypass the use of updating the FAT table and on December 1. US patent office granted patent US8. The feature, called Transaction Safe FAT, or Tex. FAT, was granted a patent by the US patent office under US7. November 3, 2. 00. When a file is accessed, the directory must be sequentially searched until a match is found.
For filenames shorter than 1. This is called a directory file set, and a 2. Mi. B sub- directory can hold up to 2,7.
When searching for a file, the file name is first converted to upper case using the upcase table (file names are case insensitive) and then hashed using a proprietary patented algorithm into a 1. Each record in the directory is searched by comparing the hash value. When a match is found, the filenames are compared to ensure that the proper file was located in case of collisions. This improves performance because only 2 bytes have to be compared for each file. This significantly reduces the CPU cycles because most filenames are more than 2 characters (bytes) in size and each comparison is virtually only performed on 2 bytes at a time until the intended file is located. Metadata and checksums.
There are three checksums currently in use. The Volume Boot Record (VBR) is a 1. BIOS Parameter Block (BPB), OEM parameters and the checksum sector. This provides integrity of the VBR by determining if the VBR was modified. The most common cause could be a boot sector virus, but this would also catch any other corruption to the VBR.
A second checksum is used for the upcase table. This is a static table and should never change. Any corruption in the table could prevent files from being located because this table is used to convert the filenames to upper case when searching to locate a file. The third checksum is in the directory file sets.
Multiple directory records are used to define a single file and this is called a file set. This file set has metadata including the file name, time stamps, attributes, address of first cluster location of the data, file lengths, and the file name.
A checksum is taken over the entire file set and a mismatch would occur if the directory file set was accidentally or maliciously changed. When the filesystem is mounted, and the integrity check is conducted, these hashes are verified. Mounting also includes comparison of the version of the ex.
FAT filesystem by the driver to make sure the driver is compatible with the filesystem it is trying to mount, and to make sure that none of the required directory records are missing (for example, the directory record for the upcase table and Allocation Bitmap are required and the filesystem can't run if they are missing). If any of these checks fail, the filesystem should not be mounted, although in certain cases it may mount read- only. The file system provides extensibility through template based metadata definitions using generic layouts and generic patterns. Microsoft also asserts software patents on ex. FAT which make it difficult to re- implement its functionality in a compatible way without violating a large percentage of them. Although ex. FAT is now widely supported, initially Mac OS X and many consumer devices could only handle FAT1. FAT1. 6, and FAT3.
The situation had formerly rendered ex. FAT, and flash memory formatted with it, impractical as a universal exchange format.
Native Linux support for ex. FAT is still limited.
FAT3. 2 implementations in other operating systems allow an unlimited number of files up to the number of available clusters (that is, up to 2. Windows 7 removes this limitation, enabling Ready. Boost caches larger than 4 Gi. B. FAT file systems instead used alternating tables, as this allowed recovery of the file system if the media was ejected during a write (which occurs frequently in practice with removable media). The optional Tex.
FAT component adds support for additional backup tables and maps, but may not be supported. Adoption. Mobile phones, PCs, and networks have a different volume pricing model. The loadable USBEXFAT driver requires Panasonic's USB stack for DOS and only works with USB storage devices; the open- source EXFAT executable is an ex. FAT filesystem reader, and requires the HX DOS extender to work.
The largest theoretical file size would be 1. Ei. B. However, since the true theoretical maximum volume size under the current specification cannot exceed 1. Pi. B, a file can never reach that file length. Another reason for the limit is that current IDE/ATA disk addressing is LBA- 4. A 5. 12 byte sector size is represented by 2. In other words, the 1. Pi. B limit on the architecture is a hardware restriction.
This scenario does not include AF (4k sectors) and ex. FAT is limited to 1.
Pi. B regardless of sector size based on the specification.^The theoretical maximum volume size is defined by up to 2. The size is currently also limited by the LBA4. With VFATs, the 1. References. January 2. Description of the ex. FAT file system driver update package .
