Formatted Capacity; Table 4-2 Formatted Capacity - Maxtor ATLAS 15K Product Manual

1. Typical specifications assume 25°C ambient temperature, nominal supply
voltages and no applied shock or vibration.
Maximum specifications assume worst case extremes of operating temperature,
humidity, and supply voltages.
2. Sequential Head Switch time 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. Sequential Cylinder Switch time is the time from the conclusion of the last
sector of a cylinder to the first logical sector on the next cylinder. It
includes sequencer overhead for write setup on head and cylinder switch.
4. Random LBA.
5. Full 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' Reset time is the time from Reset to Selection.
7. At power on start-up error algorithms are used. These recovery routines
may extend the time to Drive Ready by as much as 30 seconds.
8. Refer to Section 4.11, "DISK ERRORS" for details on error rate
definitions.

FORMATTED CAPACITY

At the factory, the Maxtor Atlas 15K 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
capacity shown.
