Seagate ST2000VN0001 ユーザーズマニュアル

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

• Active mode 

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

• Idle mode

The buffer remains enabled, and the drive accepts all commands and returns to Active mode any time disk 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 disk 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.

• Idle and Standby timers

Each time the drive performs an Active function (read, write or seek), the standby timer is reinitialized and begins counting down
from its specified delay times to zero. If the standby timer reaches zero before any drive activity is required, the drive makes a tran-
sition to Standby mode. In both Idle and Standby mode, the drive accepts all commands and returns to Active mode when disk
access is necessary.

This section provides the temperature, humidity, shock, and vibration specifications for Desktop HDDs. Ambient temperature is defined
as the temperature of the environment immediately surrounding the drive. Above 1000ft. (305 meters), the maximum temperature is
derated linearly by 1°C every 1000 ft. Refer to
