1.9 Power-up sequence

1.Power is applied to the drive.

2.When power is applied, the LED stays on for about 1 second.

3.The spindle motor reaches operating speed in about 4 seconds.

4.The magnetic actuator-lock releases the actuator.

5.The drive achieves final speed-control lock.

6.The heads position over track 0 and the drive is ready.

1.9.1Power-down sequence

Caution. Do not move the drive until the motor has come to a complete stop.

1.The power is turned off.

2.Within 15 seconds, the drive spindle stops rotating.

3.The read/write heads automatically move to the landing zone, which is inside the maximum data cylinder.

4.The magnetic actuator-lock mechanism locks the arm. This completes the power-down sequence.

1.10 Auto-park

During power-down, the read/write heads automatically move to the landing zone. The heads park inside the maximum data cylinder and the magnetic actuator-lock engages. When power is applied, the heads recalibrate to track 0.

1.11 Power specifications

1.11.1 Power management

The drive supports Active, Idle and Standby power-management modes. The power-management commands the drive supports are listed in the table on page 27. The table on page 11 shows the typical power consumption rates for each power-management mode. The test criteria for each mode is defined below. The Idle and Standby timers are disabled at the factory.
