Specifications
Maxtor Atlas 10K III 4-3
1. Typical specifications assume 25°C ambient temperature, nominal supply
voltages and no applied shock or vibration.
Maximum specifications assum e worst case extremes of operating te mperature,
humidity, and supply voltages.
2. Sequential Head Switch tim e is the time from the conclusion of the last
sector of a track to the beginning of the first logical sector on the next track
of the same cylinder. It includes sequencer overhead for write setup on head
and cylinder switch.
3. Sequentia l Cyli nder Switch t ime is the time fr om the conclu sion of th e last
sector of a cylinder to the first logical sector on the n ext c ylind er. It includes
sequencer overhead for write setup on head and cylinder switch.
4. Random LBA.
5. F ull Stroke seek is defined as a seek from cylinder 0 to maximum cylinder
or vice versa. It may include one head switch.
6. SCSI ‘Hard’ Re s e t tim e is the time fro m Reset to Se l e ctio n.
7. At power on start-up error alg orithms are used. These recovery routines
may extend the tim e to Drive Ready by as much as 30 seconds.
8. Ref e r to Se ctio n 4. 11, “DISK ERRORS” for det a il s on e rro r rate
definitions.
9. Post 48 hours Grown spec. = All capacities <10 per 1 000 hours o f
operation.
At the factory, the Maxtor Atlas 10K III receives a low-level format that creates
the actual tracks and sectors on the drive. Table 4-2 shows the capacity resulting
from this process. Formatting done at the user level for operation with DOS,
UNIX, or other operating systems, will result in less capacity than the physical
ca pacity shown.
