Formatted capacities

Seagate designs specify capacity points at certain block sizes that Seagate guarantees current and future products will meet. We rec-

Programmable drive capacity
Using the Mode Select command, the drive can change its capacity to something less than maximum. See the Mode Select (6) parameter
list table in the SAS Interface Manual, part number 100293071. A value of zero in the Number of Blocks field indicates that the drive will not
change the capacity it is currently formatted to have. A number other than zero and less than the maximum number of LBAs in the Number
of Blocks field changes the total drive capacity to the value in the Number of Blocks field. A value greater than the maximum number of
LBAs is rounded down to the maximum capacity.
