VDS_ESOF_QUICK: Determines whether a file system is quick formatted. A quick format doesnot verify each sector on the volume.VDS_ESOF_COMPRESSION: Determines whether a file system is created with compressionenabled.VDS_ESOF_DUPLICATE_METADATA: Determines whether the metadata is duplicated (UDFfile system only).2.2.1.2.19 VDS_DISK_FLAGThe VDS_DISK_FLAG enumeration defines the properties of a disk.typedef enum _VDS_DISK_FLAG{VDS_DF_AUDIO_CD = 0x1,VDS_DF_HOTSPARE = 0x2,VDS_DF_RESERVE_CAPABLE = 0x4,VDS_DF_MASKED = 0x8,VDS_DF_STYLE_CONVERTIBLE = 0x10,VDS_DF_CLUSTERED = 0x20,VDS_DF_READ_ONLY = 0x40,VDS_DF_SYSTEM_DISK = 0x80,VDS_DF_BOOT_DISK = 0x100,VDS_DF_PAGEFILE_DISK = 0x200,VDS_DF_HIBERNATIONFILE_DISK = 0x400,VDS_DF_CRASHDUMP_DISK = 0x800,VDS_DF_HAS_ARC_PATH = 0x1000,VDS_DF_DYNAMIC = 0x2000,VDS_DF_BOOT_FROM_DISK = 0x4000,VDS_DF_CURRENT_READ_ONLY = 0x8000} VDS_DISK_FLAG;VDS_DF_AUDIO_CD: The disk is an audio CD, as specified in [IEC60908].VDS_DF_HOTSPARE: The disk is a hot spare.VDS_DF_RESERVE_CAPABLE: The disk can be reserved for a host.VDS_DF_MASKED: The disk is currently hidden from the host.VDS_DF_STYLE_CONVERTIBLE: The disk is convertible between the MBR partition format andthe GPT partition format.VDS_DF_CLUSTERED: The disk is clustered.VDS_DF_READ_ONLY: The disk read-only attribute is set.VDS_DF_SYSTEM_DISK: The disk contains the system volume.VDS_DF_BOOT_DISK: The disk contains the boot volume.VDS_DF_PAGEFILE_DISK: The disk contains the paging file on one of its volumes.VDS_DF_HIBERNATIONFILE_DISK: The disk contains the hibernation file on one of itsvolumes.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 201138 / 360
VDS_DF_CRASHDUMP_DISK: The disk is configured to contain a crash-dump file on one of itsvolumes.VDS_DF_HAS_ARC_PATH: The disk has an Advanced RISC Computing (ARC) path specified inthe BIOS. For information on ARC paths, see [KB102873].VDS_DF_DYNAMIC: The disk is a logical disk manager dynamic disk.VDS_DF_BOOT_FROM_DISK: Indicates the disk from which the machine will boot. Note thatthis is BIOS disk 0 on the MBR, not the current system volume disk. For example, if themachine boots to Windows PE, this flag is set on BIOS disk 0. For EFI machines, this flag isset on a disk containing the EFI system partition used to boot the machine.VDS_DF_CURRENT_READ_ONLY: Indicates that the disk is in a read-only state. If this flag isnot set, the disk is read/write. Unlike the VDS_DF_READ_ONLY flag, which is used to indicatethe disk's read-only attribute maintained by the operating system, this flag reflects the actualdisk state. This flag cannot be set by using the IVdsDisk::SetFlags method or cleared byusing the IVdsDisk::ClearFlags method.The disk will be in a read-only state if its read-only attribute is set. However, a disk can be ina read-only state even if its read-only attribute is not set, if the underlying hardware is readonly.For example, if the LUN is in read-only state or if the disk is a virtual hard disk thatresides on a volume that is read-only, the underlying hardware is read-only and therefore thedisk is in a read-only state.2.2.1.2.20 VDS_DISK_STATUSThe VDS_DISK_STATUS enumeration defines the status of a disk.typedef enum _VDS_DISK_STATUS{VDS_DS_UNKNOWN = 0x00000000,VDS_DS_ONLINE = 0x00000001,VDS_DS_NOT_READY = 0x00000002,VDS_DS_NO_MEDIA = 0x00000003,VDS_DS_OFFLINE = 0x00000004,VDS_DS_FAILED = 0x00000005,VDS_DS_MISSING = 0x00000006} VDS_DISK_STATUS;VDS_DS_UNKNOWN: The disk status is unknown.VDS_DS_ONLINE: The disk is online.VDS_DS_NOT_READY: The disk is not ready.VDS_DS_NO_MEDIA: The disk has no media.VDS_DS_OFFLINE: The disk is offline. Offline disks have no volume devices exposed.VDS_DS_FAILED: The disk failed.VDS_DS_MISSING: The disk is missing; it is no longer available to the operating system.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 201139 / 360
