A colleague of mine remembers reading that it was possible to write
protect an IDE hard disk by writing a value to one of the controller
registers.   This disables writes to the disk and the mode can only
be undone by booting or power cycling the computer.  Anyone have a
reference or know of where I can find information on this technique?
