Removing a Backup Volume - How?!?

How can I remove a backup volume? For example, I have two volumes on my drive for two different computers I’ve backed up. I only want to remove ONE. I have even tried going through Windows Explorer to manually remove the volume and I get an error that I must have admin rights. I have admin rights on the pc so it must be talking about the Passport drive. Anyone know how to do this?

Hello dhoots, close Smartware before before trying to delete any content from the backup folder, also remember to stop the backup from the computer you no longer need to backup.
