2.2 Formatted capacity
*One Gbyte equals one billion bytes when referring to hard drive capacity. Accessible capacity may vary depending on operating environment
and formatting.
2.2.1 LBA mode
When addressing the drive 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 137 Gbytes.
2.3 Default logical geometry
LBA mode
When addressing the drive in LBA mode, all blocks (sectors) are consecutively numbered from 0 to n–1, where
