                        WARNING - this function is admin only and bypasses file system security. The resulting VHD file will contain data which currently exists on the physical disk.

Convert:            Converts an existing RAW disk image file to a fixed-format VHD. The existing file length, rounded up, will contain block data A VHD footer is appended to the current end of file.

WARNING - this function is admin only and bypasses file system security.  The resulting VHD file will contain data which currently exists on the physical disk.

Repair:              Repairs a broken Hyper-V snapshot chain where an administrator has expanded the size of the root VHD.  The base VHD will be returned to its original size. THIS MAY CAUSE DATA LOSS if the contents of the base VHD were changed after expansion.
