Locking Folders On Hard Drives?

I'm looking for a program that can run with the autorun.inf of a hard drive/memory stick which would open a simple tiny protection program against opening specific files/folders on that hard drive? for example, say i turn on the hard drive, and the computer reads the autorun.inf file and runs the protection file. I browse over to "Z:\asdf\private" and I get a little message box telling me that I need a password to access this folder (same thing goes for a file: "Z:\asdf\file.exe")

And also, protection against accessing the folders/files it from MS-DOS.

Is there a program that is ALMOST AS EQUIVALENT (if not exactly the same) as to what I want?

Thanks
