A type of partition that is an extension of a primary partition. It's possible to have many extended partitions on a hard drive.
Extended partitions were developed in response to the need for more than four partitions per disk drive. An extended partition can itself contain multiple partitions and this extends the number of partitions possible on a single drive. An extended partition is a container for logical drives that are formatted and assigned drive letters. The introduction of extended partitions was driven by increasing capacities of new disk drives.
A portion of a basic disk that can contain logical drives. Use an extended partition if you want to have more than four volumes on your basic disk. Only one of the four partitions allowed per physical disk can be an extended partition, and no primary partition needs to be present to create an extended partition. Extended partitions can be created only on basic disks. See also Basic disk, Logical drive, Partition, Primary partition, Active partition.
A combination of all the logical partitions. The extended partition has no separate physical manifestation except for the entry in the MBR. The starting location of the extended partition in the MBR is the starting location of the first partition boot record (EBR) in the extended partition. The ending location of the extended partition in the MBR is the ending location of the last logical drive in the extended partition. The extended partition consists of a linked list of partitions, each corresponding to a logical drive. See the page Extended Partition Tables for an example. A unit of information comprised of 2 words or 4 bytes (on microcomputers).
a box containing a linked list of logical
a container for storage areas known as a Logical Drives
a method for avoiding the four-partition limit and configuring a hard disk into more than four logical areas
a partition where non-system files (files other than DOS or operating system files) can be stored on a disk
a portion of a Master Boot Record (MBR) basic disk that can contain logical drives
a primary partition that has been subdivided
a primary partition that is designated to be available for carving up into additional partitions in order to increase the number of partitions to more than the maximum of four primary partitions
a primary partition that was originally developed in order to overcome the four-primary-partition limit
a primary partition which contains a lot of partitions
a separate partition that holds a kind of "boot sector" that contains a partition table with four more records
a special type of primary partition that contains logical partitions instead of primary partitions
A portion of a basic disk that can contain logical drives. To have more than four volumes on your basic disk, you need to use an extended partition. Only one of the four partitions allowed per physical disk can be an extended partition, and no primary partition needs to be present to create an extended partition. You can create extended partitions only on basic disks. See also basic disk; logical drive; partition; primary partition; unallocated space.
A segment of a disk drive that contains other partitions. See Partition.
partition of a hard disk drive divided into smaller logical sections - logical volumes. Developed to break the limit of 4 partitions per a hard disk drive, related to small size of MBR.
A type of partition that you can create only on basic master boot record (MBR) disks. Extended partitions are useful if you want to create more than four volumes on a basic MBR disk. Unlike primary partitions, you do not format an extended partition with a file system and then assign a drive letter to it. Instead, you create one or more logical drives within the extended partition. After you create a logical drive, you format it and assign it a drive letter. An MBR disk can have up to four primary partitions, or three primary partitions, one extended partition, and multiple logical drives.
