Formatting a disk for use by an operating system and its applications typically involves three different processes. [e]Low-level formatting (i.e., closest to the hardware) marks the surfaces of the disks with markers indicating the start of a recording block (typically today called sector markers) and other information like block CRC to be used later, in normal operations, by the disk ...
The file system uses an index table stored on the device to identify chains of data storage areas associated with a file, the File Allocation Table (FAT). The FAT is statically allocated at the time of formatting. The table is a linked list of entries for each cluster, a contiguous area of disk storage. Each entry contains either the number of ...

A basic data partition can be formatted with any file system, although most commonly BDPs are formatted with the NTFS, exFAT, or FAT32 file systems. To programmatically determine which file system a BDP contains, Microsoft specifies that one should inspect the BIOS Parameter Block that is contained in the BDP's Volume Boot Record.
Memory card readers, unlike smartphones, telephones and other devices, such as cameras and digital cameras, allow formatting in a file system other than FAT (FAT16, FAT32, exFAT) to NTFS in Windows, ext, ext2, ext3 in Linux or HFS, HFS + for Mac OS. Smartphones or other devices like cameras format them only in FAT.
Formatting tools or non-DR SYS-type tools may clear these bits, but other disk tools should leave bits 15-8 unchanged. 0x02A 0x1F 2 Version (defined as 0.0). The high byte of the version number is stored at offset 0x02B, and the low byte at offset 0x02A. [4] FAT32 implementations should refuse to mount volumes with version numbers unknown by them.
If you’re stuck on today’s Wordle answer, we’re here to help—but beware of spoilers for Wordle 1264 ahead. Let's start with a few hints.
exFAT does have a few advantages over FAT32, but they are irrelevant in many common use cases, where FAT(32) is used today as an exchange format on flash cards/sticks and where a relatively small number of large files is written once and not modified later on before the next delete/reformat (typically f.e. for usage in digital cameras ...
