If you cannot reformat it in Disk Utility it could possibly be a broken hard drive. It may be worth your while to open it up using [guide|381|this guide] and once you have the hard drive out of the machine shake it just a tad and if you hear any excessive rattling it is probably broken. Hope this helps.
