Why does my computer see a 3TB hard drive as 750GB?

I have a Windows XP (stop laughing) with an ECS C19A SLI motherboard. I just got a 3TB hard drive to replace my storage drive that just failed on me. When I connect my new hard drive, XP sees it as 750GB. Is my motherboard too old for an update? Help!

Why doesn't it at least see 2TB? Can I use the hard drive and then later (when I get a new computer) use it as a 3TB?
