Introduction

VhxdTool is a command line utility for Windows for rapid creation and resizing of fixed-size virtual disk files (VHDX). Vhdxtool provides similar functionality to a former utility vhdtool for Windows Server 2008/R2, but whereas vhdtool worked with older (VHD) format, vhdxtool works with the new (VHDX) format.

Attention!

The performance benefit comes at the price of data security: unlike Windows standard tools such as diskpart or New-VHD, and like a former vhdtool for VHD-files, this tool does not zero-out the newly created or resized VHDX-file and therefore it might be possible for a user to access data that previously existed on the underlying physical hard disk by running data forensics tools inside the virtual machine the disk will be attached to. As such you should only use this tool when you fully understand all the implications.
