VDS_DISK_EXTENT_TYPE enumeration

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Defines the set of disk extents types. The type can be a partition, volume, or free space.

Syntax

typedef enum _VDS_DISK_EXTENT_TYPE { 
  VDS_DET_UNKNOWN   = 0,
  VDS_DET_FREE      = 1,
  VDS_DET_DATA      = 2,
  VDS_DET_OEM       = 3,
  VDS_DET_ESP       = 4,
  VDS_DET_MSR       = 5,
  VDS_DET_LDM       = 6,
  VDS_DET_CLUSTER   = 7,
  VDS_DET_UNUSABLE  = 0x7FFF
} VDS_DISK_EXTENT_TYPE;

Constants

VDS_DET_UNKNOWN

An extent of any unknown partition.

VDS_DET_FREE

An extent of free space, including free space inside an extended partition.

VDS_DET_DATA

An extent of any volume.

VDS_DET_OEM

An extent of an OEM partition.

VDS_DET_ESP

An extent of an ESP partition.

VDS_DET_MSR

An extent of a MSR partition.

VDS_DET_LDM

An extent of a LDM metadata partition.

VDS_DET_CLUSTER

An extent of a cluster metadata partition.

VDS_DET_UNUSABLE

An extent of unusable space on a disk. That is, space outside the four primary partitions (or three primary partitions plus one extended partition) on a basic MBR disk and space outside the dynamic disk public region.

Remarks

ESP, MBR, and LDM metadata partitions are partition styles on GPT disks only.

The VDS_DISK_EXTENT structure includes a VDS_DISK_EXTENT_TYPE value as a member to indicate an existing disk extent type.

Note  Additional constants might be added to the VDS_DISK_EXTENT_TYPE enumeration in future Windows versions. For this reason, your application must be designed to gracefully handle an unrecognized VDS_DISK_EXTENT_TYPE enumeration constant.
