okay wayne. time to call on your advice again.

I have to give an account on my 2000 machine to someone I don't fully trust. Fine. Except I still have 2 fat32 partitions with sensitive data (and other OSes) on them. Is there anyway to deny access to them by regular users? I know Window's built-in security only works on NTFS, but is there anything from MS or a 3rd party that will work FAT? Even something as crude as blocking the entire drive is fine.
