Power Mode Definitions

Spin-up

The drive is spinning up following initial application of power and has not yet reached full speed.

Seek

A random access operation by the disk drive.

Read/Write

Data is being read from or written to the drive.

Idle

The drive is spinning, the actuator is parked and powered off and all other circuitry is powered on. The drive is capable of responding to read commands within 40 ms.

Standby

The spin motor is not spinning. The drive will leave this mode upon receipt of a command that requires disk access. The time-out value for this mode is programmable. The buffer is active to accept write data.

Sleep

This is the lowest power state – with the interface set to inactive. A software or hardware reset is required to return the drive to the Standby state.

EPA Energy Star Compliance

Maxtor Corporation supports the goals of the U.S. Environmental Protection Agency’s Energy Star program to reduce the electrical power consumption of computer equipment.
