Diskpart can be used to extended the volume in Windows. I have listed the steps and results below on how I did it on my computer. This is with the understanding that you have already added the the new hardisk to the existing volume using the utilities that comes with your hardware. In my case I used the Dell OpenManage Server Administrator to do this first.
From the command line execute the diskpart.exe utility.
C:\>diskpart
