Maxtor 10K III manual Formatted Capacity, Number of 512-byte

Specifications

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.

9.Post 48 hours Grown spec. = All capacities <10 per 1000 hours of operation.

￿￿￿(14/#66'&At the factory,￿%#2#%+6;the Maxtor Atlas 10K III receives a low-level format that creates the actual tracks and sectors on the drive. Table 4-2shows 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.
