IT World.com shares the following 5 ways to expand a virtual hard drive.

1. Follow Benjamin Guinebertière's blog post concerning how he managed to do this. Gotta love robocopy!

2. Try the image-based approach outlined in Christian Saborío's blog post. What, never heard of BartPE?

3. Get VHD Utility from Xtralogic. Costs $24.95. There's also a trial version you can download and use for 30 days but it only increases a VHD by 1 GB. The geeky thing would be to write a batch file that kept incrementing the size of your VHD until it reaches the size you need.

4. Use VHD Resizer, which is part of the vmToolkit. I'm not sure if this costs anything-I tried to download it but it asked me to sign in, and geeks don't like signing into things.

5. Create a second VHD and add it to your virtual machine, then move as much as you can from your system disk to your new data disk.
