Did you read my post? I said to "use the uid, gid, and/or mode mount options (see man mount) to restrict access to non-unix filesystems like fat32."
The only thing to do with chown/chmod would be to change the mount point's permissions , if it is what you want. Using chown on files on a fat32 partition is useless.
