In this age of virtualization I typically try to size a Windows system volume to a realistic size. That is, a size that will provide a good cushion, but not over allocating space. Occassionally, I do screw up and I need extend the volume. Now, one cannot resize a live system volume with diskpart, even if you have sufficient space on that disk. With additional data type volumes, one can add the space necessary to the LUN, run diskpart and extend the volume.

When I came into work today I noticed that I wasn’t able to power up a newly created VM in our ESX 3.5 cluster. Within a couple minutes of searching I came across this blog post from Leo.
