I have a MacBook Pro with Snow Leopard, and Windows 7 Premium installed via Boot Camp v3.0 (equal 64GB partitions on a 128GB SSD). Both OSs are running fast and smoothly without any major issues except for the following: - When I am logged into Snow Leopard, I can open and access all the folders and files for all users on the Windows 7 partition (but you cannot write to them). - When I am logged into Windows 7, I can open and access all the folders and files for all users on the Snow Leopard partition (but you cannot write to them). I need to stop this accessibility (even if its just on one side). Does anyone know how? All accounts have passwords on them, and it doesnt matter whether the logon is an admin or a regular user, files can be accessed and viewed on each OS partition from both sides regardless. Is this a huge flaw, or did Apple do this on purpose? Why bother setting up logons and passwords with file and folder restrictions within each OS, only to be able to (easily) access all these files and folders while logged on to another OS? Anyone know how to break this link? In my mind, while in Snow Leopard, when I click on a Windows 7 Admin users folder, I should be getting a message stating that access is denied (and vice versa when logged into Windows 7). I think that file viewing should be limited to Shared Folders only. Is it just me? Am I doing something wrong?
