These were the text mode fdisk and the GUI-based fdiskpm. OS/2 shipped with two partition table managers up until version 4.0. This limitation applies to all versions of fdisk supplied with Windows 95 OSR 2.1, Windows 98 and Windows ME.
The original Windows 98 fdisk program size is smaller than the updated one.įdisk cannot create partitions larger than 512 GB, despite that the maximal FAT32 partition size is 2 TB. Microsoft named the replacement "263044usa8" and is Version. An updated fdisk is available from Microsoft that corrects this. The fdisk supplied with Windows 95 does not report the correct size of a hard disk that is larger than 64 GB.
The fdisk /mbr switch is undocumented but well known for repairing the master boot record. (However, to create an extended partition any partition editor must put extended boot records before each logical drive on the disk.) Users must be sure the correct disk/partition has been chosen before using a DOS/Windows fdisk for partitioning. Unlike the fdisk programs for other operating systems, the fdisk 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. Windows 2000 and later do not use fdisk, they have the Logical Disk Manager feature, as well as diskpart. Only those fdisk versions shipping with Windows 95B or later are able to manipulate FAT32 partitions. Most DOS fdisk programs, including the fdisk program that came with the original Windows 95, are only capable of creating FAT partitions of types FAT12, FAT16 and FAT16B.Ī derivative of the MS-DOS fdisk was provided with Windows 95, Windows 98, and later Windows ME. Support for FAT16B was added with Compaq MS-DOS 3.31, and later became available with MS-DOS/PC DOS 4.0. MS-DOS versions 2.0 through 3.10 included OEM specific partitioning tools, which may or may-not be called fdisk. The command is available in MS-DOS versions 3.2 and later.

IBM PC DOS 7.10 contained FDISK32 and FORMAT32 utilities. In April 1987, PC DOS/fdisk 3.30 added support for extended partitions, which could hold up to 23 "logical drives" or volumes. In August 1984, PC DOS 3.0 added FAT16 partitions to support larger hard disks more efficiently. 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 fdisk did not support them. fdisk writes the master boot record, which supported up to four partitions. Version 1 could be used to create one FAT12 DOS partition, delete it, change the active partition, or display partition data. IBM introduced fdisk, 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. Similar utilities exist for Unix-like systems, for example, BSD disklabel. In versions of the Windows NT operating-system line from Windows 2000 onwards, fdisk is replaced by a more advanced tool called diskpart. fdisk features in the DOS, DR FlexOS, IBM OS/2, and Microsoft Windows operating systems, and in certain ports of FreeBSD, NetBSD, OpenBSD, DragonFly BSD and macOS for compatibility reasons. In computing, the fdisk command-line utility provides disk-partitioning functions, preparatory to defining file systems.
