3.6 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 maxi-
mum capacity.
3.7 Factory-installed options
You may order the following items which are incorporated at the manufacturing facility during production or pack-
aged 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 planning 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.
