8 Barracuda 36ES Product Manual, Rev. H

3.5 Unformatted and formatted capacities

Formatted capacity depends on the number of spare reallocation sectors reserved and the number of bytes per

sector. The following table shows the standard OEM model capacities:

Notes.

[1] Sector size selectable at format time. Users having the necessary equipment may modify the data block

size before issuing a format command and obtain different formatted capacities than those listed. See

Mode Select command and Format command in the

SCSI Interface Product Manual

, part number

75789509.

[2] User available capacity depends on spare reallocation scheme selected, the number of data tracks per

sparing zone, and the number of alternate sectors (LBAs) per sparing zone.

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 Parameter List table in the

SCSI Interface Product Manual

, part number 75789509. Refer to the

Parameter list block descriptor number of blocks field. A value of zero in the number of blocks field indicates

that the drive shall not change the capacity it is currently formatted to have. A number in the number of blocks

field that is less than the maximum number of LBAs changes the total drive capacity to the value in the block

descriptor number of blocks field. A value greater than the maximum number of LBAs is rounded down to the

maximum capacity.
