Fdisk
fdisk is a command-line utility for disk partitioning. It has been part of DOS, DR FlexOS, IBM OS/2, and early versions of Microsoft Windows, as well as certain ports of FreeBSD, NetBSD, OpenBSD, DragonFly BSD and macOS for compatibility reasons. Windows 2000 and its successors have replaced fdisk with a more advanced tool called diskpart.
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 supports up to four partitions. The other three were intended for other operating systems such as CP/M-86 and Xenix, which were expected to have their own partitioning utilities.
Microsoft first added fdisk to MS-DOS in version 3.2. MS-DOS versions 2.0 through 3.10 included OEM-specific partitioning tools, which may have been named fdisk.
PC DOS 3.0, released in August 1984, added support for FAT16 partitions to handle larger hard disks more efficiently. PC DOS 3.30, released in April 1987, added support for extended partitions. (These partitions do not store data directly but can contain up to 23 logical drives.) In both cases, fdisk was modified to work with FAT16 and extended partitions. Support for FAT16B was first added to Compaq's fdisk in MS-DOS 3.31. FAT16B later became available with MS-DOS and PC DOS 4.0.
The undocumented /mbr switch in fdisk, which could repair the master boot record, soon became popular.
IBM PC DOS 7.10 shipped with the new fdisk32 utility.
ROM-DOS, DR DOS 6.0 FlexOS, PTS-DOS 2000 Pro, and FreeDOS, include an implementation of the fdisk command.
Windows 95, Windows 98, and Windows ME shipped with a derivative of the MS-DOS fdisk. Windows 2000 and its successors, however, came with the more advanced[according to whom?] diskpart and the graphical Disk Management utilities.
