Starwind V2V converter is a free software which allows converting VHD to VMDK virtual disk files. It allows to convert VHD to VMDK virtual disk file format. VMware converter, which has been updated recently to version 6.1, does need Hyper-V server running in order to connect to and convert hyper-V virtual machine into VMware VMs.
But what to do when you recover just the VHD files on some external USB, or you downloaded some Microsoft preview software, like the ones released recently for SCVMM 2012 R2. Those come as VHD files (I have put links to the bottom of this article, in case you're intereted).
Some thoughts. During the virtualization beginnings, when VMware Workstation 1-2.x was the latest release of virtualization products together with Connectix Virtual PC and both products were good starting points to spin multiple OS on a desktop computer and learn new OSes. During that time already the cool idea of converting VHD to VMDK and vice versa was running in my head.
Things has evolved since and Virtual PC we all know where it is now and how many guest OS it supports now. Not many (Wikipedia)…. But VHD (and the new VHDX) formats are here for Hyper-V, as well as VMDK for VMware. To convert VHD to VMDK you need a tool.
The one which works pretty well is Starwind V2V Converter. It's a free tool and enables the multiple conversion possibilities. It allows VHD to VMDK conversion, and also a conversion into thin VMDK which allows save disk space by not allocating the whole space, but only the blocks that are used.
There can be several use cases when you encounter VHD or VHDX disk file format which you want to convert, and depending on the situation, not every time it's possible to use Starwind V2V converter as it does not support VHDX:
Case 1 – You have hyper-V server running
Use VMware converter to connect directly to the Hyper-V host and convert the VM.
Case 2 – You have just the VHDX
Can be the case if some customer lost the server and all he has is the VHDX file. In this case you can user PowerShell to convert the VHDX into VHD and then use Starwind V2V converter to convert the file into VMDK.
Open a PowerShell window where is the .vhdx file and execute the following command:
PS C:> Convert-VHD –Path c:testMY-VM.vhdx –DestinationPath c:testMY-NEW-VM.vhd
The reason for converting VHD into VMDK might just be that you can be running your lab on ESXi and don't want to break your lab just to test new software available as trial VHDs, so a conversion which is fairly quick can help you out with that.

There are other free tools to convert VHD into VMDK and vice versa, one of them is WinImage. But it's commercial (paid) software. There might be other tools as well, but I haven't tested those recently. If you know any other tools which you know that works, just share your knowledge in the comment section.
