introduced, Fixed Disk Setup Program version 1.00, with the March 1983 release of the IBM PC/XT, the first PC to store data on a hard disk, and the IBM Personal Computer DOS version 2.0. Version 1 could be used to create one FAT12 DOS partition, delete it, change the active partition, or display partition data. writes the master boot record, which supported 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 as did not support them. In August 1984, PC DOS 3.0 added FAT16 partitions to support larger hard disks more efficiently. In April 1987, PC DOS/fdisk 3.30 added support for extended partitions, which could hold up to 23 "logical drives" or volumes. IBMPC DOS 7.10 contained and utilities.
Microsoft DOS and Windows
The command is available in MS-DOS versions 3.2 and later.. MS-DOS versions 2.0 through 3.10 included OEM specific partitioning tools, which may or may-not be called FDISK. Support for FAT16B was added with Compaq MS-DOS 3.31, and later became available with MS-DOS/PC DOS 4.0. Most DOS programs, including the program that came with the original Windows 95, are only capable of creating FAT partitions of types FAT12, FAT16 and FAT16B. A derivative of the MS-DOS was provided with Windows 95, Windows 98, and later Windows ME. Only those versions shipping with Windows 95B or later are able to manipulate FAT32 partitions. Windows 2000 and later do not use, they have the Logical Disk Manager feature, as well as. Unlike the programs for other operating systems, the programs for DOS and Windows 9x/Me not only alter data in the partition table, but will also overwrite many sectors of data in the partition itself. Users must be sure the correct disk/partition has been chosen before using a DOS/Windows for partitioning. The switch is undocumented but well known for repairing the master boot record. The supplied with Windows 95 does not report the correct size of a hard disk that is larger than 64 GB. An updated is available from Microsoft that corrects this. Microsoft named the replacement "263044usa8" and is Version 4.72.2811.0. Signature May 23, 2000. The original Windows 98 program size is smaller than the updated one. Despite the fact that FAT32 allows you to create a single partition up to 2TB and format it, FDISK cannot create partitions larger than 512GB. Applies to all versions of FDISK from a DOS floppy disk in Windows 95 OSR 2.1 / Windows 98 / ME. However, the great advantage of the FDISK program is the ability to create a partition on a USB stick and memory cards in a very simple way and to format it. Microsoft DiskPart from Windows Vista to Windows 10 has blocked the ability to display and format all flash drives including flash drives and memory cards including SD. The only possibility of using Microsoft FDISK or outside of Microsoft's use of the program, e.g. Symantec GDISK which enables such a function.
shipped with two partition table managers up until version 4.0. These were the text modefdisk and the GUI-based fdiskpm. The two have identical functionality, and can manipulate both FAT partitions and the more advanced HPFS partitions. OS/2 versions 4.5 and higher can use the JFS filesystem as well as FAT and HPFS, and replace with the Logical Volume Manager.
DR/Novell DOS and FlexOS
and FlexOS include an implementation of the command.
ROM-DOS
includes an implementation. ROM-DOS was introduced in 1989 as an MS-DOS compatible operating system designed for embedded systems. ROM-DOS 7.1 added support for FAT32 and long file names.
for Mach Operating System was written by Robert Baron. It was ported to 386BSD by Julian Elischer, and the implementation is being used by FreeBSD, NetBSD and DragonFly BSD, all as of 2019, as well as the early versions of OpenBSD between 1995 and 1997 before OpenBSD 2.2. Tobias Weingartner re-wrote in 1997 before OpenBSD 2.2, which has subsequently been forked by Apple Computer, Inc in 2002, and is still used as the basis for on macOS as of 2019. For native partitions, BSD systems traditionally use BSD disklabel, and partitioning is supported only on certain architectures and only in addition to the BSD disklabel.
Linux
In Linux, fdisk is a part of a standard package distributed by the Linux Kernel organization, util-linux. The original program was written by Andries E. Brouwer and A. V. Le Blanc and was later rewritten by Karel Zak and Davidlohr Bueso when they forked the util-linux package in 2006.
