Resizing a VHD (Virtual Hard Drive)

1. Download VHD Resizer from http://vmtoolkit.com/files/folders/converters/entry87.aspx

2. Select the Source vhd to resize.

3. Fill in the full path to the destination vhd and the name of the vhd. Example: C:\Virtual Images\blah.vhd.

2. Type in the size that you want the hard drive to be.

3. Click the resize button. (Note: This is kind of resource intensive.)

 

4. On a computer with Virtual Server 2005 R2 SP1 installed, open a command prompt window.

5. Change to the directory C:\Program Files\Microsoft Virtual Server\vhdmount

6. Type the command vhdmount /p <Path to vhd file>\vhdfilename and hit return. Example: vhdmount /p "C:\Virtual Images\VSIMAGE.vhd"

7. You should see a message about the virtual hard drive being plugged in. At some point you will probably also see an Autoplay window pop up.

8. In the command window type diskpart and hit return.

 

9. WARNING: Since the drive is plugged into your computer, if you select the wrong drive you could potentially trash your computer.

 

10. Type list disk and hit return. On my computer this returned this.

17. Fire up the Virtual Image that you named in step 3.

 

18. Once the Virtual machine loads you will see a message about adding your hardware and then it will want to reboot. Let it, and you should be good to go.
