GHOST could clone a disk or partition to another disk or partition or to an image file. GHOST allows for writing a clone or image to a second disk in the same machine, another machine linked by a parallel or network cable, a network drive, or to a tape drive. 3.1 uses 286 with XMS and could still run on OS/2.

GParted is used for creating, deleting, [3] resizing, [4] moving, checking, and copying disk partitions and their file systems. This is useful for creating space for new operating systems, reorganizing disk usage, copying data residing on hard disks, and mirroring one partition with another (disk imaging). It can also be used to format a USB drive.
The protective MBR is stored at LBA 0, and the GPT header is in LBA 1, with a backup GPT header stored at the final LBA. The GPT header has a pointer to the partition table (Partition Entry Array), which is typically at LBA 2. Each entry on the partition table has a size of 128 bytes.
TestDisk reads sectors on the storage device to determine if the partition table or filesystem on it requires repair (see next section). TestDisk is able to recognize the following partition table formats: [2] Apple partition map; GUID Partition Table; Humax; PC/Intel Partition Table (master boot record) Sun Solaris slice; Xbox fixed ...
The BIOS boot partition is a partition on a data storage device that GNU GRUB uses on legacy BIOS-based personal computers in order to boot an operating system, when the actual boot device contains a GUID Partition Table (GPT). Such a layout is sometimes referred to as BIOS/GPT boot.
Additionally, KDE Partition Manager can back up file systems to files and restore such backups. [4] [5] It uses util-linux to detect and manipulate devices and partition tables while several (optional) file system tools provide support for manipulating file systems. These optional packages will be detected at runtime and do not require a ...
GRUB 2, elilo and systemd-boot serve as conventional, full-fledged standalone UEFI boot managers (a.k.a. bootloader managers) for Linux. Once loaded by a UEFI firmware, they can access and boot kernel images from all devices, partitions and file systems they support, without being limited to the EFI system partition.
All three programs are written in C and are part of the util-linux package of Linux utility programs. Since sfdisk is command-driven instead of menu-driven, i.e., it reads input from standard input or from a file, it is generally used for partitioning drives from scripts or used by programs, like e.g. GParted.
