*Display of total bytes varies from file systems.**Cylinders, heads or sectors are not applicable for these capacities. Only LBA
addressing applies LBA count addressed in the table above indicates total user storage capacity and will remain the same
throughout the lifespan of the device. However, the total usable capacity of the CFast is most likely to be less than the total physical
capacity because a small portion of the capacity is reserved for device maintenance usages.
