IBM introduced the first version of fdisk (officially dubbed "Fixed Disk Setup Program") in March 1983, with the release of the IBM PC/XT computer (the first PC to store data on a hard disk) and the IBM PC DOS 2.0 operating system. fdisk version 1.0 can create one FAT12 partition, delete it, change the active partition, or display partition data. fdisk writes the master boot record, which ...
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 ...
In contrast to fdisk and cfdisk, sfdisk is not interactive. [1] All three programs are written in C and are part of the util-linux package of Linux utility programs. Since sfdisk is command-driven instead of menu-driven, i.e., it reads input from standard input or from a file, it is generally used for partitioning drives from scripts or used by ...
The partitions themselves may also contain data to describe more complex partitioning schemes, such as extended boot records (EBRs), BSD disklabels, or Logical Disk Manager metadata partitions. [8] The MBR is not located in a partition; it is located at a first sector of the device (physical offset 0), preceding the first partition.
A partition table is a table maintained on a disk by the operating system that outlines and describes the partitions on that disk. [11] The terms partition table and partition map are similar terms and can be used interchangeably.
A block, a contiguous number of bytes, is the minimum unit of storage that is read from and written to a disk by a disk driver.The earliest disk drives had fixed block sizes (e.g. the IBM 350 disk storage unit (of the late 1950s) block size was 100 six-bit characters) but starting with the 1301 [8] IBM marketed subsystems that featured variable block sizes: a particular track could have blocks ...

The FDISK command manipulates hard disk partition tables. The name derives from IBM's habit of calling hard drives fixed disks. FDISK has the ability to display information about, create, and delete DOS partitions or logical DOS drive. It can also install a standard master boot record on the hard drive.
