Disk utility will do it but I think you must erase it all and start backup again, or use it for something else.

Right click on the drive in Disk Utility and then select Erase and a format. I use Mac OS Extended (case-sensitive, journaled, encrypted). You can create a new Time Machine backup after it formats.
