Actually, most software-based hard disk protection systems modify the
boot sector and the hard disk partition tables at the very least.  I
have even seen one that did a simple shift encryption on *EVERYTHING*,
but I didn't trust it.
Any hard disk is a candidate for disk locking via software, whether XT,
AT, or other.
