Hello George, Reformatting drives is done with the Disk Utility application, but before you reformat your drive, or erase your partition, you might want to try doing some troubleshooting.
Here's the link to the Apple Knowledge Base article on Time Machine: Troubleshooting backup issues: http://support.apple.com/kb/ht3275 I think there's probably more information in the Take Control of Backing Up You Mac eBook guide, if you have this (one of the perquisites of being a list member is the 80% discount in buying any of the Take Control Guides). HTH.
