The partitioning or division of a large hard drive into smaller units. A single, large Physical Drive can be partitioned into two or more smaller Logical Drives.
A drive recognised by the operating system with a unique identifier such as C or D. A single physical drive can act as several logical drives, each with its own identifier.
The internal division of a large hard disk into smaller units. One single physical drive may be organized into several logical drives for convenience; DOS supports up to 23 logical drives on a system. On a single-floppy system, the disk drive can function as both logical drive A and logical drive B, depending on the exact circumstances.
A disk drive that the operating system (OS) recognizes.
A drive that has been created by the disk operating system (DOS). This is done either at the preference of the user or because the DOS version does not allow a formatted capacity in excess of 32MB. A user with a 100MB hard disk will want to use more than 32MB, so a program will tell DOS there are a bunch of "logical" drives that add up to 100MB. DOS 5.0 eliminates this need.
A subpartition of an extended partition on a hard disk. See also extended partition.
A logical drive is a partition you create within an extended partition on a basic disk. A logical drive can be formatted and assigned a drive letter. Only basic disks can contain logical drives. A logical drive cannot span multiple disks. See also Basic disk, Basic volume, Extended partition.
A group of physical drives, or part of a group, that behaves as one storage unit. Each constituent physical drive contributes the same storage volume to the total volume of the logical drive. Has performance advantages over individual physical drives.
A collection of physical disks combined into a RAID array and viewed by the user as one large drive.
a different type of partition
a name assigned by the operating system to a physical device or several physical devices collectively
an area of the extended DOS partition that you can set up to group directories and files
an array of independent physical drives
an extension of an existing drive
a partition in a physical array of disks that is made up of contiguous data segments on the physical disks
a physically contiguous area of disk storage, which is a portion of the extended partition
a pointer to a physical disk drive in your system
a portion of a hard drive that the operating system will manage as an individual drive
a portion of the hard drive that an operating system can manage
a section of the hard disk that appears to be a separate drive in a directory structure
a set of physical drives grouped together under a single RAID level
a virtual disk constructed from one or (usually) more than one physical disks
a whole disk or any part of a disk that is set up so Windows will treat it as a separate drive
A virtual drive within an array that can consist of more than one physical drive. Logical drives divide the contiguous storage space of an array of hard drives or a spanned group of arrays of drives. The storage space in a logical drive is spread across all the physical drives in the array or spanned arrays.
A portion or all of a hard drive partition that is treated by the operating system as though it were a physical drive. Each logical drive is assigned a drive letter, such as drive C, and contains a file system. Also called a volume.
The operating system's internal representation of a drive. It may refer to an actual disk device, or to a group of directories specified using the SUBST command.
A sub-partition of an extended partition on a hard disk.
Typically, a group of hard disks logically combined to form a single large storage unit. More broadly, the assignment of an ID to a drive or drives for use in storage management. Often abbreviated, "LD."
Section of the hard drive the OS sees as a physical drive.
A complete or partial representation of a logical array. The storage space in a logical drive is spread across all the physical drives in the array or spanned arrays. Each RAID controller can be configured with up to forty logical drives in any combination of sizes. Configure at least one logical drive for each array. A logical drive can be in one of three states: Online: All participating disk drives are online. Degraded: (Also "Critical") a single drive in a redundant array (not RAID 0) is not online. Data loss can occur if a second disk drive fails. Offline: Two or more drives in a redundant array (not RAID 0) or one or more drives in a RAID 0 array are not online. I/O operations can be performed only with logical drives that are online or degraded.
A volume that you create within an extended partition on a basic master boot record (MBR) disk. Logical drives are similar to primary partitions, except that you are limited to four primary partitions per disk, whereas you can create an unlimited number of logical drives per disk. A logical drive can be formatted and assigned a drive letter. See also: basic disk; basic volume; drive letter; extended partition; master boot record (MBR); primary partition; volume
