Power Requirements
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.
