Abstract
Communication between a host and a data storage device (DSD) including a first media for storing data and a second media for storing data. In one embodiment, a first controller of the DSD is configured to control operation of the first media and a second controller of the DSD is configured to control operation of the second media. The first controller receives a key data block of a monitoring system from the host with the key data block including a task file. The key data block is evaluated to determine if the key data block is directed to the second media, and if it is determined that the key data block is directed to the second media, the task file of the key data block is sent from the first controller to the second controller.
