How to rename a BOOTCAMP Volume?

Hey all,

I've recently switch the HDD in my MBP to a Samsung HDD. I had Bootcamp installed on the previous drive so I had to partition and reinstall Windows 7 the computer. Back when I had bootcamp on my other HDD, the disk showed the name "BOOTCAMP" under the Volume. Now on the new HDD it says "Untitled". I want to change the name to BOOTCAMP but the normal ways I change a name for a volume or file wont work. I've tried opening up Disk Utility but I had no luck. Any idea as to what I can do?

Thanks!
