Many partition table manipulators are known as fdisk. Before use, hard disks must be divided into one or more logical disks called partitions. This division is described in the partition table found in sector 0 of the disk.
1 DOS fdisk
All the many DOS operating systems, including MS-DOS, PC-DOS and DR-DOS use a partition table manipulator known as fdisk. The name derives from IBM's habit of calling hard drives fixed disks. DOS fdisk programs are only capable of creating the FAT type partitions that DOS uses.
A derivitate of the MS-DOS fdisk was provided with Windows 95, Windows 98, and Windows Me. Versions shipping with Windows 95B and higher were able to manipulate FAT-32 partitions.
2 Linux fdisk
Linux needs at least one partition, namely for its rootIn computer file systems, the root directory is the first directory in a hierarchy. It can be likened to the root of a tree the starting point where all branches originate. To use the example of a physical file cabinet, if the separate drawers in the file file systemSee Filing system for this term as it is used in libraries and offices In computing, a file system is a method for storing and organizing computer files and the data they contain to make it easy to find and access them. File systems may use a storage devi. It can use swapVirtual memory is a computer design feature that permits software to use more memory than the computer physically possesses. In technical terms, it allows software to run in a memory address space whose size and addressing are not necessarily tied to the files and/or swap partitions, but the latter are more efficient. So, usually one will want a second Linux partition dedicated as a swap partition. On Intel compatible hardware, the BIOSIn computing, the Basic Input-Output System or BIOS is computer interface code that locates and loads the operating system into RAM. It provides low-level communication, operation and configuration to the hardware of a system, which at a minimum drives th that boots the system can often only access the first 1024 cylinders of the disk. For this reason people with large disks often create a third partition, just a few MB large, typically mounted on /boot, to store the kernel image and a few auxiliary files needed at boot time, so as to make sure that this stuff is accessible to the BIOS. There may be reasons of security, ease of administration and backup, or testing, to use more than the minimum number of partitions.

It is functionally identical to fdisk, but with a graphical user interface ( GUI). Although the GUI is intended to m.
3 OS/2 fdisk
OS/2OS/2 is an operating system created by Microsoft and IBM and later developed by IBM exclusively. The name stands for "Operating System/2", because it was intended as the preferred operating system for IBM's " Personal System/2 ( PS/2)" line of second-gene shipped with two partition table managers up until version 4.0. These were the text modeA text mode program communicates with the user by only displaying text and possibly a limited set of predefined semi-graphical characters, which allow to draw rudimentary boxes around portions of text, either to highlight the content or to simulate widget fdisk 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 (including EcomStation ) can use the JFS filesystem as well as FAT and HPFS, and replace fdisk with the Logical Volume Manager, LVM.
