This document discusses disk management techniques. Basic disks use traditional partitioning with up to four primary partitions or three primary partitions and an extended partition containing multiple logical drives. Dynamic disks provide more flexibility than basic disks by not using traditional partitioning and allowing multiple volumes per disk through a hidden database that tracks volume information. A volume is a storage area on a hard disk that is formatted with a file system and assigned a drive letter, and a disk can have multiple volumes or a volume can span multiple disks.

Basic disk Uses traditional disk management techniques Contains primary partitions, extended partitions, and logical drives Basic disks can contain up to four primary partitions, or three primary partitions and an extended partition with multiple logical drives. Dynamic disk Does not use traditional partitioning Provides flexibility in number of volumes per disk A physical disk that provides features that basic disks do not, Dynamic disks use a hidden database to track information about dynamic volumes on the disk and other dynamic disks in the computer.
