I have installed Windows 7 on my MacBook Pro, and my question is pretty simple. When I go into Mac OS X, I can click on the Windows 7 hard drive and see its documents. I want to prevent that. I don't want people logged into my Mac to see my business files that I work with in Windows 7. Is there a way to privatize my Windows 7 hard drive so that it isn't accessible to Mac OS X? Basically I want people to click on Finder and not be able to visit the "Windows 7" device. I'm sure it must be simple, some way to block permissions to view that folder. Also, when you use "search for" you can still see some of the text files I opened in Windows 7 pop up.
