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

Seek

A random access operation by the drive.

Read/Write

Data is being randomly 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 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.
