2.1.1 Formatted capacity
*One Gbyte equals one billion bytes when referring to hard drive capacity. Accessible capacity may vary depending on operating environ-
ment and formatting.
2.1.1.1 LBA mode
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 4.4, "Identify Device command" (words 60-61 and 100-103) for additional information about 48-bit
addressing support of drives with capacities over 137 Gbytes.
