(*1) The formatted capacity can be changed by changing the logical block length and using spare sector
space. See Chapter 3 for the further information. The formatted capacity listed in the table is an
estimate for 512 bytes per sector.
estimate for 512 bytes per sector.
(*2) One gigabyte (GB) = one billion bytes; accessible capacity will be less and actual capacity depends
on the operating environment and formatting.
