I have a void Time Machine backup on my drive. My main drive is tittle Super Drive. I have backups for Super Drive & Super Drive 1.... why am i getting second backup for my drive? It is an old folder that hasn't been modified in months. Finder will not let me delete in manually, and I can't see it in Time Machine mode because it is not an accurate backup. I need to get rid of these to clear some space on my backup drive.
