Disk Management

Disk Management in Windows 2000 is responsible for creating, deleting, altering, and maintaining storage volumes in a system. Windows 2000 features significant improved manageability and recoverability of volumes in a Windows 2000 environment. This is achieved by the introduction of dynamic disks and a new snap-in. Windows 2000 supports two volume managers: basic disks and legacy Ftdisk volume sets are managed by FTDisk and the Ftdisk.sys driver; dynamic disks and all new volume sets are managed by Logical Disk Manager (LDM) and the Dmio.sys driver. Figure 2.6 shows the Disk Management architecture.

Unlike in Microsoft® Windows NT® version 4.0 and earlier, volume set configuration metadata is stored and replicated with other Disk Management metadata and is not stored in the registry.
