I have two internal drives in a MacPro Hexcore 3.33 machine running under 10.8.3 that will not retain or remember that I have checked the box in the drive finder window, 'Ignore Ownership On This Volume' box when rebooting. It only happens on this one specfic machine. I have the same OS installed on three other machines. Is this an OS glitch? Any way to get this to hold?
