Running Server 2003 I have tried to extend the partition of the system(C:) drive using ubcd partition utilities. After restarting, I check in Disk Management and it correctly shows the partition is now 34GB but in My Computer it shows 25.8 used and 2.72 free which gives a partition size of 28.52 which is wrong. How is Disk management showing the correct new partition size yet my computer doesnt recognize that and how can I correct this?

extend volume does not work because it says "the volume you have selected may not be extended." even if there is free space still on the drive. I assume this is because this is the system partition.

FYI: I already have SP2 installed which includes this hotfix but it may be a good reference for others. I came across this kb addressing the error message I was receiving.

The workaround I used was connect the vhd from this virtual machine to a different virtual machine as a secondary drive. I was then able to sucessfully use the extend command. When I swapped the vhd back to the original VM as the boot drive, it showed the correct available free space!

NOTE: Please make sure you have a backup of the drive. Especially if you're working with VHD like me its so easy to quickly created a copy before making changes.

To extend a partition there has to be unallocated space directly after  the partition you want to extend.
Unallocated space and free space are two completely different terms.  Free space is space available on an already formatted partition. Unallocated space is space on the drive that has not been formatted and is thus available to the formatted partition directly before it.

Use Partition Wizard Home  Edition (free) to extend partitions. It is more powerful than any other partition manager I know as far as extending partitions.
