Refers to PEs as PPs (physical partitions), and to LEs as LPs (logical partitions). Does not have a copy-on-write snapshot mechanism; creates snapshots by freezing one volume of a mirror pair.

The larger LBA size supports larger disks. Some BIOSes support GPT partition tables as well as MBR partition tables, in order to support larger disks than MBR partition tables can support. GPT uses universally unique identifiers (UUIDs), which are also known as globally unique identifiers (GUIDs), to identify partitions and partition types.
Each partition then appears to the operating system as a distinct "logical" disk that uses part of the actual disk. System administrators use a program called a partition editor to create, resize, delete, and manipulate the partitions. [3] Partitioning allows the use of different filesystems to be installed for different kinds of files.
Disk cloning is the process of duplicating all data on a digital storage drive, such as a hard disk or solid state drive, using hardware or software techniques. [1] Unlike file copying, disk cloning also duplicates the filesystems, partitions, drive meta data and slack space on the drive. [2]

Ranish Partition Manager is a freeware hard disk partition editor, disk cloning utility, and boot manager, that gives a high level of control for creating multi-boot systems. [1] [2] It is available on the freeware live CD SystemRescueCD and the Ultimate Boot CD (not the Windows version).
To allow the use of more FAT partitions in a compatible way, a new partition type was introduced in PC DOS 3.2 (1986), the extended partition (EBR), [14] which is a container for an additional partition called logical drive. Since PC DOS 3.3 (April 1987), there is another, optional extended partition containing the next logical drive, and
A logical disk, logical volume or virtual disk (VD [1] or vdisk [2] for short) is a virtual device that provides an area of usable storage capacity on one or more physical disk drive(s) in a computer system. The disk is described as logical or virtual because it does not actually exist as a single physical entity in its own right. The goal of ...
