Formatted capacities
Standard OEM models are formatted to 512 bytes per block. The block size is selectable at format time and must be a multiple of 4 bytes.
Users having the necessary equipment may modify the data block size before issuing a format command and obtain different formatted
capacities than those listed.
To provide a stable target capacity environment and at the same time provide users with flexibility if they choose, Seagate recommends
product planning in one of two modes:
1. Seagate designs specify capacity points at certain block sizes that Seagate guarantees current and future products will
meet. We recommend customers use this capacity in their project planning, as it ensures a stable operating point with
backward and forward compatibility from generation to generation. The current guaranteed operating points for this prod-
uct are

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.

Factory-installed options
Users may order the following items which are incorporated at the manufacturing facility during production or packaged before shipping.
Some of the options available are (not an exhaustive list of possible options):
• Other capacities can be ordered depending on sparing scheme and sector size requested.
• Single-unit shipping pack. The drive is normally shipped in bulk packaging to provide maximum protection against transit
damage. Units shipped individually require additional protection as provided by the single unit shipping pack. Users plan-
ning single unit distribution should specify this option.
• The Safety and Regulatory Agency Specifications, part number 75789512, is usually included with each standard OEM
drive shipped, but extra copies may be ordered.
