VHD tool

Introduction
VHD tool is an unmanaged code command-line tool which provides useful VHD manipulation functions including instant creation of large fixed-size VHDs. The source code is included.

Requirements
A computer running one of the following Windows operating systems:
Server: Windows Server 2003 or above
Client: Windows XP or above
NTFS file system

Usage

VhdTool.exe /create <FileName> <Size> [/quiet]
VhdTool.exe /convert <FileName> [/quiet]
VhdTool.exe /extend <FileName> <NewSize> [/quiet]
VhdTool.exe /repair <BaseVhdFileName> <FirstSnapshotAVhdFileName> [/quiet]

Create: Creates a new fixed format VHD of size <Size>.
        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.

Extend: Extends an existing fixed format VHD to a larger size <Size>.
         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.
