Consider the following scenario:
This issue occurs because the VHD and the file system on the host computer do not recognize that the physical hard disk is full.
To prevent this issue, verify that the physical disk has sufficient hard disk space to mount the VHD and to perform the required operations. If the VHD is mounted with an undo disk (This is the default setting.), you must have free hard disk space that is double the size of the VHD.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
The VHD communicates at the driver level to the file system on the host computer. Therefore, the VHD does not recognize that the physical hard disk is full. Additionally, the file system on the host computer does not recognize that the physical hard disk is full. The file system interprets the write failure as disk corruption.
Note When this issue occurs, the file system on the host computer does not correctly release the VHD file handle when you cancel the copy operation, and then you unmount the VHD. Therefore, you must restart the host computer.
