extending a virtual hard drive vhd for Virtual PC / Virtual Server

I saw this good link http://blog.donnfelker.com/post/Resizing-a-VHD-and-a-Volume.aspx to extend virtual hard disks. I change it a bit and here is what I did:

(please check as well the good post http://kb.dutchalps.com/microsoftvirtualpc.htm)

To extend the VHD you need to use a tool called VHResizer from the host. It is really good. Then add the new drive as a secundary HD of some virtual machine (does not need to be the one you are going to use that VHD - I used a Windows XP VM. In Disk management from windows, right click the just extended space and create a volume.

Then use the diskpart.exe command line tool from microsoft to extend the volume.

VMWare ESX has a tool for that included on the product called vmkfstools.
