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 .
In August 2024, Microsoft released an update to Windows 11 preview builds that allows for the creation of FAT32 partitions up to 2TB in size. [42] The maximal possible size for a file on a FAT32 volume is 4 GB minus 1 byte, or 4,294,967,295 (2 32 − 1) bytes. This limit is a consequence of the 4-byte file length entry in the directory table ...
11 Partition Volume Label, padded with blanks (0x20), e.g., "NO␠NAME␠␠␠␠" Software changing the directory volume label in the file system should also update this entry, but not all software does. The partition volume label is typically displayed in partitioning tools since it is accessible without mounting the volume.
The partition type (or partition ID) in a partition's entry in the partition table inside a master boot record (MBR) is a byte value intended to specify the file system the partition contains or to flag special access methods used to access these partitions (e.g. special CHS mappings, LBA access, logical mapped geometries, special driver access, hidden partitions, secured or encrypted file ...
Each partition then appears to the operating system as a distinct "logical" disk that uses part of the actual disk. System administrators use a program called a partition editor to create, resize, delete, and manipulate the partitions. [3] Partitioning allows the use of different filesystems to be installed for different kinds of files.
The layout of a disk with the GUID Partition Table. In this example, each logical block is 512 bytes in size and each entry has 128 bytes. The corresponding partition entries are assumed to be located in LBA 2–33. Negative LBA addresses indicate a position from the end of the volume, with −1 being the last addressable block.
FIPS (First nondestructive Interactive Partition Splitter) [1] - is an MS-DOS program for non-destructive splitting of File Allocation Table (FAT) hard disk partitions. Splitting partitions is an alternative to deleting the partitions and creating new ones using software such as fdisk , the advantage of which is that the data is not lost.
— Microsoft documents a version 4.0 BPB and a new "FAT32 BIOS Parameter Block (BPB)" (a version 7.0 BPB) for DOS-Windows 98 that is "larger than a standard BPB", has an "identical structure to a standard BPB", but that also "includes several extra fields".
