2.8.4Power-management modes

The drive provides programmable power management to provide greater energy efficiency. In most systems, you can control power management through the system setup program. The drive features the following power-management modes:

Table 4:	Power management modes

Power modes		Heads		Spindle	Buffer

Active (operating)		Tracking		Rotating	Enabled

Idle		Tracking		Rotating	Enabled

Idle, active		Floating		Rotating	Disabled

Idle, low power		Parked		Rotating	Disabled

Standby		Parked		Stopped	Enabled

Sleep		Parked		Stopped	Disabled

•Active mode

The drive is in Active mode during the read/write and seek operations.

•Idle mode

The buffer remains enabled in performance mode, and the drive accepts all commands and returns to Active mode any time disc access is necessary.

•Standby mode

The drive enters Standby mode when the host sends a Standby Immediate command. If the host has set the standby timer, the drive can also enter Standby mode automatically after the drive has been inactive for a specifiable length of time. The standby timer delay is established using a Standby or Idle command. In Standby mode, the drive buffer is enabled, the heads are parked and the spindle is at rest. The drive accepts all commands and returns to Active mode any time disc access is necessary.

•Sleep mode

The drive enters Sleep mode after receiving a Sleep command from the host. In Sleep mode, the drive buffer is disabled, the heads are parked and the spindle is at rest. The drive leaves Sleep mode after it receives a Hard Reset or Soft Reset from the host. After receiving a reset, the drive exits Sleep mode and enters Standby mode with all current translation parameters intact.
