Boot from a USB key and then format your drive.

You have to un-mount the drive first. Boot from the Ubuntu CD or USB flash drive, or form within Ubuntu, if its a second drive, and use disks to do that. Just type disks in Dash, when the window open up, click on the little square, to un-mount as shown in the image below:

Once un-mounted, then you can format it, by clicking on the little gears, and choose Format.
