m_bCommandQueueing: A Boolean value that indicates whether the device supports multipleoutstanding commands.m_BusType: A value from the VDS_STORAGE_BUS_TYPE enumeration that indicates the bustype of the device.m_szVendorId: The null-terminated vendor identification Unicode string of the device. Thisvalue is NULL if no vendor ID exists.m_szProductId: The null-terminated product identification Unicode string of the device. Thisvalue is NULL if no product ID exists.m_szProductRevision: The null-terminated product revision Unicode string of the device. Thisvalue is NULL if no product revision information exists.m_szSerialNumber: The null-terminated serial number of the device. This value is NULL if noserial number exists.m_diskSignature: The disk signature of the disk.m_deviceIdDescriptor: A VDS_STORAGE_DEVICE_ID_DESCRIPTOR structure thatcontains the identification descriptor of the device.m_cInterconnects: The number of elements in the m_rgInterconnects array.m_rgInterconnects: Any array of VDS_INTERCONNECT structures that describe the physicalinterconnects to the device.2.2.1.3.17 VDS_FILE_SYSTEM_PROPThe VDS_FILE_SYSTEM_PROP structure provides information about the properties of a filesystem.typedef struct _VDS_FILE_SYSTEM_PROP {VDS_FILE_SYSTEM_TYPE type;VDS_OBJECT_ID volumeId;unsigned long ulFlags;ULONGLONG ullTotalAllocationUnits;ULONGLONG ullAvailableAllocationUnits;unsigned long ulAllocationUnitSize;[string] WCHAR* pwszLabel;} VDS_FILE_SYSTEM_PROP,*PVDS_FILE_SYSTEM_PROP;type: A VDS_FILE_SYSTEM_TYPE value that provides information about the type of the filesystem.volumeId: The VDS object ID of the volume object on which the file system resides.ulFlags: The combination of any values, by using the bitwise OR operator, that are defined inthe VDS_FILE_SYSTEM_PROP_FLAG enumeration.ullTotalAllocationUnits: The total number of allocation units on the file system.ullAvailableAllocationUnits: The number of allocation units available on the file system.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 201152 / 360
ulAllocationUnitSize: The size of the allocation units in use by the file system.pwszLabel: A null-terminated Unicode label of the file system.2.2.1.3.18 VDS_FILE_SYSTEM_FORMAT_SUPPORT_PROPThe VDS_FILE_SYSTEM_FORMAT_SUPPORT_PROP structure provides information about filesystems that are supported for formatting volumes.typedef struct _VDS_FILE_SYSTEM_FORMAT_SUPPORT_PROP {unsigned long ulFlags;unsigned short usRevision;unsigned long ulDefaultUnitAllocationSize;unsigned long rgulAllowedUnitAllocationSizes[32];WCHAR wszName[32];} VDS_FILE_SYSTEM_FORMAT_SUPPORT_PROP,*PVDS_FILE_SYSTEM_FORMAT_SUPPORT_PROP;ulFlags: The combination of any values, by using the bitwise OR operator, that are defined inthe VDS_FILE_SYSTEM_FORMAT_SUPPORT_FLAG enumeration.usRevision: A 16-bit, binary-coded decimal number that indicates the file system version, ifany. The first two (most significant) digits (8-bits) indicate the major version while the lasttwo (least significant) digits (8-bits) indicate the minor version. For example, a value that hasa bit pattern of 00000010 01010000 (0x0250 in hexadecimal) represents version 2.50;0x1195 represents version 11.95, and so on.ulDefaultUnitAllocationSize: The default allocation unit size, in bytes, that the file systemuses for formatting the volume. This value MUST be a power of 2 and MUST also appear inrgulAllowedUnitAllocationSizes.rgulAllowedUnitAllocationSizes: A zero-terminated array of allocation unit sizes, in bytes,that the file system supports for formatting the volume. An array is not zero-terminated if thearray contains 32 elements. Each of the values in the array MUST be a power of 2.wszName: A null-terminated Unicode wide-character string that indicates the name of the filesystem.2.2.1.3.19 VDS_DISK_EXTENTThe VDS_DISK_EXTENT structure provides information about a disk extent.typedef struct _VDS_DISK_EXTENT {VDS_OBJECT_ID diskId;VDS_DISK_EXTENT_TYPE type;ULONGLONG ullOffset;ULONGLONG ullSize;VDS_OBJECT_ID volumeId;VDS_OBJECT_ID plexId;unsigned long memberIdx;} VDS_DISK_EXTENT,*PVDS_DISK_EXTENT;[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 201153 / 360
