1. A data storage device comprising:
- a data storage medium;
a drive interface including a terminal for outputting an activity indicator signal, the activity indicator signal operable to be coupled to a light emitting diode, illumination of the diode to indicate an activity at the data storage device; and
a drive controller coupled to the data storage medium and to the drive interface, the drive controller to;
access an operational parameter at the device;
encode the operational parameter using a serial data protocol;
superimpose the encoded operational parameter on the activity indicator signal; and
provide the activity indicator signal to a data storage management device, the data storage management device configured to manage operation of the data storage system based on the encoded operational parameters.

Abstract
An operational parameter is accessed at a data storage device. The operational parameter is encoded using a serial data protocol. The encoded operational parameter is superimposed on an activity indicator signal outputted by the data storage device. The activity indicator signal is configured to be coupled to a light emitting diode.
