[MS-VDS]: Virtual Disk Service (VDS) Protocol Specification

Section 3.4.5.2.32.3: An access path can apply to a drive letter or an empty folder on anNTFS file system. Section 3.4.5.2.32.3: Due to an inconsistency in the Windows code, only one notification issent. Rather than sending VDS_MOUNT_POINT_NOTIFICATION with ulEvent asVDS_NF_MOUNT_POINT_CHANGE and VDS_DRIVE_LETTER_NOTIFICATION with ulEvent asVDS_NF_DRIVE_LETTER_FREE, Windows sends VDS_MOUNT_POINT_NOTIFICATION withulEvent VDS_NF_MOUNT_POINT_CHANGE (0x000000CD). Section 3.4.5.2.32.3: Mounted folder path names cannot be assigned to hidden volumes. Ahidden volume is one that is not reported to the Mount Point Manager because: (1) theGPT_BASIC_DATA_ATTRIBUTE_HIDDEN flag is set, (2) the partition type is not recognized, (3) thepartition type is a known OEM partition type, or (4) the partition type is eitherPARTITION_SYSTEM_GUID (an ESP partition) or PARTITION_MSFT_RECOVERY_GUID (a recoverypartition). Section 3.4.5.2.32.6: Due to an inconsistency in the Windows code, only one notification issent. Rather than sending VDS_MOUNT_POINT_NOTIFICATION with ulEvent asVDS_NF_MOUNT_POINT_CHANGE and VDS_DRIVE_LETTER_NOTIFICATION with ulEvent asVDS_NF_DRIVE_LETTER_FREE, Windows sends VDS_MOUNT_POINT_NOTIFICATION withulEvent as VDS_NF_MOUNT_POINT_CHANGE. (0x000000CD). Section 3.4.5.2.32.8: For Windows Server 2003,Windows Server 2003 R2, Windows Vista,Windows Server 2008: If the volume is offline, the VDS_VF_PERMANENTLY_DISMOUNTED flagis set in the ulFlags member of the VDS_VOLUME_PROP (section 2.2.2.13.1.1) orVDS_VOLUME_PROP2 (section 2.2.2.14.1.1) structure, but the volume status is not updated toVDS_VS_OFFLINE. Section 3.4.5.2.33.3: On Windows 7 and Windows Server 2008 R2, if the method call ismade using FAT, FAT32, or ExFAT file system types, and the bEnableCompression parameter isTRUE, VDS_E_COMPRESSION_NOT_SUPPORTED will be returned in the return value of this methodcall. On Windows Server 2003, Windows Server 2003 R2, Windows Vista, and Windows Server 2008,the parameter will be ignored. Section 3.4.5.2.33.3: On Windows 7 and Windows Server 2008 R2, if the method call ismade using FAT, FAT32, or ExFAT file system types, and the bEnableCompression parameter isTRUE, VDS_E_COMPRESSION_NOT_SUPPORTED will be returned in the return value of this methodcall. On Windows Server 2003, Windows Server 2003 R2, Windows Vista, and Windows Server 2008,the parameter will be ignored. Section 3.4.5.2.34.2: On Windows 7 and Windows Server 2008 R2, if the method is calledwith an Options parameter that includes the VDS_ESOF_COMPRESSION flag and a file system typeof FAT, FAT32, or ExFAT, the method will return VDS_E_COMPRESSION_NOT_SUPPORTED. WindowsServer 2003, Windows Server 2003 R2, Windows Vista, and Windows Server 2008 ignore this flag inthe Options parameter. The NTFS file system supports compression. Section 3.4.5.2.35.2: The Shrink method works only on volumes that have NTFS or RAWfile systems; otherwise, Shrink returns VDS_E_CANNOT_SHRINK (HRESULT of 0x8004251E). Section 3.4.5.2.35.2: The NTFS file system supports shrinking, the FAT file systems do not. Section 3.4.5.2.35.2: If the file system on the volume supports shrinking, shrink the filesystem following the parameters specified to the method. Section 3.4.5.2.37.4: Only one new disk can be passed to this method at a time. Section 3.4.5.2.37.4: Only one new disk can be passed to this method at a time.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011349 / 360
