Actually, another way of doing it (outside the "normal" means of DOS) is to build a "non-DOS" partition, then use a custom DOS device driver to handle it. Note that you don't even have to use a DOS file system (in fact, from a security standpoint, it probably better not to). This alternate partition can then be encrypted for additional security, if desired. I've written a similar driver (actually mine was to allow very fast I/O by "raw" dumping to a non-DOS partition), but the concept should be the same; unfortunately the source is not public domain.
