How do I create a new volume with unallocated space on 3TB hard drive

[harry1511]

Hi,
I currently just set up my new build. I decided to go with Western Digital Caviar Green 3TB for my hard drive. However, I split the hard drive into two parts: 2 TB and roughly about 770 GB unallocated space. I installed Window 7 on 2TB partition. Now, I decide to use the rest of 770 GB of unallocated space.

I tried to use Computer Management, but it doesn't give me the option to create a new volume from unallocated space. Similar thing happened with EaseUS Partition Master. With Acronis Disk Director, it doesn't even recognize the unallocated space at all!!! So how can I create a new volume or even merge it with my C drive? Do I have to reformat my hard drive and split them again and do a clean installation again?

Note:

• I already checked, my BIOS recognizes my hard drive with 3 TB.
• The unallocated space is right after my C drive.
• There is only 1 primary MBR partition (C drive), and 100 MB system files right before it.

Please help me, since I don't want to waste such a large amount of space like that...T_T

You need to use a GPT setup.

thank you, I will give it a try. That means I have to do a clean installation though...
