A mass storage data protection system for use with a mass storage device in
a gaming machine to protect the mass storage device from unauthorized
commands. The mass storage data protection system includes a mass storage
device command latch, a timing circuit for timing signals between the mass
storage device command latch and the mass storage device, a comparator and
a comparator command register in communication with the comparator. The
comparator command register includes commands that generate a fault within
the mass storage data protection system such that when the comparator
receives a command from the mass storage device command latch
corresponding to the command within the comparator command register, a
fault is generated within the mass storage command latch.
