1.7.2 Power-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 3 seconds, the motor begins to spin down.

3. The read/write heads automatically move to the shipping zone, which

is inside the maximum data cylinder.

4. The actuator-lock mechanism locks the arm. This completes the

power-down sequence.

Upon power-down, the read/write heads automatically move to the

shipping zone. The heads park outside the maximum data cylinder and

the locking mechanism engages. When power is applied, the heads

recalibrate to track 0.

The drives supports Active, Idle, Standby and Sleep power-management

modes. The power-management commands the drive supports are listed

in the table on page 27. The table on page 10 shows the average typical

power consumption rates for each power-management mode. Each

mode is defined in the section following the table.

All measurements were taken at the drive's power connector. A true RMS

meter is used to measure all modes except Standby. A DMM is used for

Standby measurements.
