Operations

∙

∙

Standby mode

Sleep mode

The drive moves from the Active mode to the idle mode by itself.

Regardless of whether the power down is enabled, the device enters the idle mode. The device also enters the idle mode in the same way after power-on sequence is completed.

And, the automatic power-down is executed if no command is coming for 30 min. (default)

(1) Active mode

In this mode, all the electric circuit in the device are active or the device is under seek, read or write operation.

A device enters the active mode under the following conditions:

∙

∙

A command other than power commands is issued.

A reset command is received.

(2) Idle mode

In this mode, circuits on the device is set to power save mode.

The device enters the Idle mode under the following conditions:

∙

∙

∙

After completion of power-on sequence.

After completion of the command execution other than SLEEP and STANDBY commands.

After completion of the reset sequence

(3) Standby mode

In this mode, the VCM circuit is turned off and the spindle motor is stopped.

The device can receive commands through the interface. However if a command with disk access is issued, response time to the command under the standby mode takes longer than the active or Idle mode because the access to the disk medium cannot be made immediately.

The drive enters the standby mode under the following conditions:

∙

∙

∙

A STANDBY or STANDBY IMMEDIATE command is issued in the active or idle mode.

When automatic power down sequence is enabled, the timer has elapsed.

A reset is issued in the sleep mode.
