Missing a Terabyte

I'm a bit old school.  I am sad to say that I have been using fdisk for half of my life.  I can count on one hand how many times I have used a graphical program to partition a hard disk.  Imagine my surprise when I realized my 3TB hard disk only had 2TB free!  It turns out MBR partition tables don't support hard disks larger than 2TB.  To partition a bigger hard disk, you have to use a GUID Partition Table (GPT).  According to the Wikipedia article, fdisk doesn't support GPT.  I guess I have to learn a new partition tool.
