Windows – Why can I not shrink the disk volume down more than 50% of original size on Server 2008

I have a new server with 540 GB disk on one partition. I decided to shrink the volume down so I could have a couple of partitions for various reasons. I could only shrink the volume by 50%. I went back in later thinking maybe I could shrink it again, but I can't. Running Windows Server Standard 2008 x64 SP2. Used disk management for resize.

Why is that, is there any way around it? Do I need a 3rd party utility and if so are there any good free/cheap/trials that I could use to do what I need and then clean it off afterwards?

This a missing feature of the windows tool. NTFS stores some management information at the middle of a partition. Of you would resize beyond 50% this information would be lost as the windows tool cannot move it.

Use a third party tool as most can resize beyond 50%.
