VDS_DISK_EXTENT_TYPE enumeration (vds.h)

  • Article

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]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
Value: 0
An extent of any unknown partition.
VDS_DET_FREE
Value: 1
An extent of free space, including free space inside an extended partition.
VDS_DET_DATA
Value: 2
An extent of any volume.
VDS_DET_OEM
Value: 3
An extent of an OEM partition.
VDS_DET_ESP
Value: 4
An extent of an ESP partition.
VDS_DET_MSR
Value: 5
An extent of a MSR partition.
VDS_DET_LDM
Value: 6
An extent of a LDM metadata partition.
VDS_DET_CLUSTER
Value: 7
An extent of a cluster metadata partition.
VDS_DET_UNUSABLE
Value: 0x7fff
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.
