Section 3.4.5.2.27.4: On Windows 7 and Windows Server 2008 R2, if the method call is madeusing FAT, FAT32, or ExFAT file system types, and the bEnableCompression parameter is TRUE,VDS_E_COMPRESSION_NOT_SUPPORTED will be returned in the return value of this method call.On Windows Server 2003, Windows Server 2003 R2, Windows Vista, and Windows Server 2008, theparameter will be ignored. Section 3.4.5.2.27.4: On Windows 7 and Windows Server 2008 R2, if the method call is madeusing FAT, FAT32, or ExFAT file system types, and the bEnableCompression parameter is TRUE,VDS_E_COMPRESSION_NOT_SUPPORTED will be returned in the return value of this method call.On Windows Server 2003, Windows Server 2003 R2, Windows Vista, and Windows Server 2008, theparameter will be ignored. Section 3.4.5.2.28.1: 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 3.4.5.2.30.4: No more than 32 disks are used with a volume; therefore, this valuewill not exceed 31. Section 3.4.5.2.30.4: If the file system on the volume is an NTFS file system, extend the filesystem to fill the newly extended volume. Section 3.4.5.2.30.4: On Windows Server 2003, Windows Server 2003 R2, Windows Vista,Windows Server 2008, Windows 7, and Windows Server 2008 R2 when the Extend operation hascompleted successfully, calling IVdsAsync::QueryStatus returns S_OK in the pHrResult outputparameter, but incorrectly returns 0 in the pulPercentCompleted output parameter. When theoperation has completed successfully, IVdsAsync::QueryStatus is expected to return 100 in thepulPercentCompleted output parameter. Section 3.4.5.2.30.5: Only an NTFS file system or raw volumes support this operation. Thismethod is not implemented on Windows Server 2003 or Windows Server 2003 R2. Section 3.4.5.2.30.5: The Shrink will only work on volumes with an NTFS file system orRAW file systems; otherwise, it returns VDS_E_CANNOT_SHRINK (HRESULT of 0x8004251E). Section 3.4.5.2.30.5: The NTFS file system supports shrinking, the FAT file systems do not. Section 3.4.5.2.30.5: If the file system on the volume supports shrinking, shrink the filesystem following the parameters specified to the method. Section 3.4.5.2.30.5: On Windows Server 2003 R2 when the Shrink operation has completedsuccessfully, calling IVdsAsync::QueryStatus returns S_OK in the pHrResult output parameter but[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011347 / 360
