One GB equals one billion bytes when referring to hard drive capacity.
Accessible capacity may vary depending on operating environment and formatting.
LBA Counts for drive capacities greater than 8TB are calculated based upon
Note
the SFF-8447 standard publication.
2.2.1
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 4.3.1, "Identify Device command" (words 60-61 and 100-103) for additional information about 48-bit addressing support
of drives with capacities over 137GB.
