ORMATTED 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:
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 product
are shown below.

ROGRAMMABLE 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.

INSTALLED OPTIONS
You 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.
