New data blocks initialize incorrectly when a differencing VHD is expanded in Windows

This issue occurs if you use the CreateVirtualDisk parameter to create a disk by expanding from a parent virtual hard disk (VHD). When you do this, you set the ParentPath parameter to a non-null value and set the MaximumSize parameter to a value that is larger than the parent disk size. In this situation, the expanded VHD is corrupted in Windows 8.1, Windows Server 2012 R2, Windows 8, or Windows Server 2012.
