3.5Formatted 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 read capacities data. Total LBAs = read capacity data (shown below) +1.
| Formatted |
| (data block size |
| 512 bytes/sector) [1] |
ST336705 | 445DCC9h (36.704 GB) [2] |
ST318405 | 222EE55h (18.352 GB) [2] |
ST39205 | 111772Ah (9.176 GB) [2] |
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.
3.6Programmable 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.
3.7Factory installed accessories
OEM Standard drives are shipped with the Cheetah 36XL Installation Guide, part number 75789518, and the Safety and Regulatory Agency Specifications, part number 75789512, unless otherwise specified.
