Can't create a second volume on 3 GG hard drive

I can't create a second volume on 3 GG hard drive (see the attached screenshot).

This 3 GB hard drive already has a primary partition of 2 GB.

What do I need to do to be able to create a second 1 GB partition within the second volume?

Is this something that can be done using Server 2008 R2 or do we need to wait until Windows 8 and the next version of Windows server are released in order to be able to use the full hard drive capacity of a 3 GB hard drive?

This is a limitation of MBR disks.  Basically, you'll have to backup, wipe the disk and make it a GPT type disk to gain access to the rest of the disk - and that assumes you've got EFI/UEFI instead of or in addition to BIOS.  Typically, for most people, It's best to use such large disks as second or additional drives and not primary drives.  For more information google EFI and GPT disks

from a command prompt
list disk
select disk #  << the number of the correct disk you want to work with
start diskmgmt.msc

Disk Management will tell you the drive needs to be initialized and it will ask you
gpt or mbr  .. select GPT

@Ve3ofa, you really should mention that your instructions will COMPLETELY WIPE that 3 GB drive.

@leew: if you had looked at the screenshot provided you would have noticed that it was RAW and not formatted, ergo there was no information to lose

If I could have looked at the screen shot I would have - I was on my phone.
But EVEN THEN, you should still post that warning - other people read this question and maybe they aren't using a raw disk.  Anyone blindly following your directions could lose data.  They SHOULDN'T be blindly following ANYONE's directions, but it happens too often that they do.
