I just got a new computer and I attached my harddrive to it. This is my first computer with spotlight. To my horror when I search in spotlight it shows all of my personal files on the harddrive. How do I stop this. I see that I can prevent searching of the hard drive but I would have to set that up on each user and they would be able to turn it off, not to mention that they would like to search there own files on the hard drive. How do I protect my sensitive information.
