A packet based high bandwidth copy protection method is described that includes the following operations. The drive mechanism may be used in a wide variety of applications where omnidirectional vehicles are advantageous, such as forklifts, aircraft maintenance platforms, robotic systems, wheelchairs, and recreational vehicles. The fluid here is maintained at a pressure and pumped at a rate to provide a sufficiently short dwell time to maintain the fluid in a supracritical state thus avoiding vapor lock. Otherwise, the data are corrected, the data in the buffer are replaced with the corrected data, and the corrected data are written to the memory.
