After searching, using, and losing documents to certain password protect sofware applications, I finally found one that works the way I want it to.
Password Protect USB, is awesome. I have it installed on my Maxtor HD, and am now able to share that drive, while keeping prying eyes out of just certain folders and sub folders. http://www.password-protect-software.com and for $39.95 not a bad bargain.
