FreeDOS: GNU GPLv2. 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, [2] NetBSD, [3] OpenBSD, [4] DragonFly BSD [5] and macOS [6] for compatibility reasons. Windows 2000 and its successors have replaced fdisk with a ...
The GUID Partition Table is specified in chapter 5 of the UEFI 2.8 specification. [2] GPT uses 64 bits for logical block addresses, allowing a maximum disk size of 2 64 sectors. For disks with 512‑byte sectors, the maximum size is 8 ZiB (2 64 × 512‑bytes) or 9.44 ZB (9.44 × 10²¹ bytes). [1] For disks with 4,096‑byte sectors the ...
Main article: CHKDSK. CHKDSK verifies a storage volume (for example, a hard disk, disk partition or floppy disk) for file system integrity. The command has the ability to fix errors on a volume and recover information from defective disk sectors of a volume. The command is available in MS-DOS versions 1 and later.
A master boot record (MBR) is a type of boot sector in the first block of partitioned computer mass storage devices like fixed disks or removable drives intended for use with IBM PC-compatible systems and beyond. The concept of MBRs was publicly introduced in 1983 with PC DOS 2.0. The MBR holds the information on how the disc's sectors (aka ...
In contrast to the Windows 9x series, the Windows NT-derived 32-bit operating systems (Windows NT, 2000, XP and newer), developed alongside the 9x series, do not contain MS-DOS compatibility as a core component of the operating system nor do they rely on it for bootstrapping, as NT was not with the level of support for legacy MS-DOS and Win16 ...
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 ...

OS/2 2.0 was the first 32-bit release of OS/2, and the first to feature the Workplace Shell. OS/2 2.0 was released in April 1992. At the time, the suggested retail price was US$195, while Windows retailed for $150. [32] OS/2 2.0 provided a 32-bit API for native programs, though the OS itself still contained some 16-bit code and drivers.
