Hoping someone can help me out with this. I am running XP Home SP 3. I have two local users (no networking) one is an admin (me) the the other is a limited user. I would like to hide two internal harddrives and one external (USB) harddrive from the limited user and restrict them from accessing it. So when I log in, I want to see and be able to acces (read/wrtie) to all the drives. When the limited user logs in, I do not want them to see or be able to access the drives - ideally they would only be able to access their 'Documents' folder. Can this be accomplished in XP Home, or do I need to upgrade to XP PRo, Vista, 7? If I do upgrade, how difficult is it to accomplish this? I have tried using TweakUI, but this only works on the admin account (option for hiding does not show up when logged in as limited user). I would consider setting up an additonal limited user for me if that would help.
