: The virtual hard disk is corrupted. The block allocation table in the virtual hard disk is corrupt.[2]0xC03A000B
: The system does not support this version of the virtual hard disk. The block size is invalid.[2]0xC03A000C
: The virtual hard disk is corrupted. The block bitmap does not match with the block data present in the virtual hard disk.[2]0xC03A000D
: The chain of virtual hard disks is broken. The system cannot locate the parent virtual hard disk for the differencing disk.[2]0xC03A000E
: The chain of virtual hard disks is corrupted. There is a mismatch in the identifiers of the parent virtual hard disk and differencing disk.[2]0xC03A000F
: The chain of virtual hard disks is corrupted. The time stamp of the parent virtual hard disk does not match the time stamp of the differencing disk.[2]0xC03A0010
: Failed to read the metadata of the virtual hard disk.[2]0xC03A0011
: Failed to write to the metadata of the virtual hard disk.[2]0xC03A0012
: The size of the virtual hard disk is not valid.[2]0xC03A0013
: The file size of this virtual hard disk is not valid.[2]0xC03A0014
: A virtual disk support provider for the specified file was not found.[2]0xC03A0015
: The specified disk is not a virtual disk.[2]0xC03A0016
: The chain of virtual hard disks is inaccessible. The process has not been granted access rights to the parent virtual hard disk for the differencing disk.[2]0xC03A0017
: The chain of virtual hard disks is corrupted. There is a mismatch in the virtual sizes of the parent virtual hard disk and differencing disk.[2]0xC03A0018
: The chain of virtual hard disks is corrupted. A differencing disk is indicated in its own parent chain.[2]0xC03A0019
: The chain of virtual hard disks is inaccessible. There was an error opening a virtual hard disk further up the chain.[2]0xC03A001A
: The requested operation could not be completed due to a virtual disk system limitation. Virtual hard disk files must be uncompressed and unencrypted and must not be sparse.[2]0xC03A001B
: The requested operation cannot be performed on a virtual disk of this type.[2]0xC03A001C
: The requested operation cannot be performed on the virtual disk in its current state.[2]0xC03A001D
: The sector size of the physical disk on which the virtual disk resides is not supported.[2]0xC03A001E
: The disk is already owned by a different owner.[2]0xC03A001F
: The disk must be offline or read-only.[2]0xC03A0020
: Change Tracking is not initialized for this virtual disk.[2]0xC03A0021
: Size of change tracking file exceeded the maximum size limit.[2]0xC03A0022
: VHD file is changed due to compaction, expansion, or offline updates.[2]0xC03A0023
: Change Tracking for the virtual disk is not in a valid state to perform this request. Change tracking could be discontinued or already in the requested state.[2]0xC03A0024
: Change Tracking file for the virtual disk is not in a valid state.[2]0xC03A0025
: The requested resize operation could not be completed because it might truncate user data residing on the virtual disk.[2]0xC03A0026
: The requested operation could not be completed because the virtual disk's minimum safe size could not be determined.
This may be due to a missing or corrupt partition table.[2]0xC03A0027
: The requested operation could not be completed because the virtual disk's size cannot be safely reduced further.[2]0xC03A0028
: There is not enough space in the virtual disk file for the provided metadata item.[2]0xC03A0029
: The specified change tracking identifier is not valid.[2]0xC03A002A
: Change tracking is disabled for the specified virtual hard disk, so no change tracking information is available.[2]0xC03A0030
: There is no change tracking data available associated with the specified change tracking identifier.[2]0x803A0001
: The virtualization storage subsystem has generated an error.[2]
