Abstract
A system and method for verifying the contents of a mass storage device attached to a computing system having a processor and system random access memory. The computing system is preferably used as part of a computer controlled gaming machine. The mass storage device has computer readable data stored therein. First, a mass storage verification module having a set of computer executable instructions for use in verifying the contents of the mass storage device is storing onto the mass storage device. Next, the method mass storage verification data for use in verifying the contents of the mass storage device is also stored onto the mass storage device. Before permitting an initial access to the computer readable data from the mass storage device contents of the mass storage device is verified by executing the instructions contained within the mass storage verification module to generate a set of computed verification data and comparing the set of computed verification data with the mass storage verification data. Finally, additional access to the computer readable data stored on the mass storage device is allowed only if the set of computed verification data matches the mass storage v…
