When addressing these drives in LBA mode, all blocks (sectors) are consecutively numbered from 0 to n–1, where n is the number of 
guaranteed sectors as defined above.

See Section 6.3.1, "Identify Device command" (words 60-61 and 100-103) for additional information about 48-bit addressing support of 
drives with capacities over 137GB.
