Data storage devices which contain firmware typically implement security features such a digitally signed firmware to protect against malicious attacks. Typically in a digitally signed firmware implementation a data storage device would validate the authenticity of the firmware during a firmware download operation. The storage device may or may not validate the authenticity of the firmware at each reboot or power cycle. A user may desire to query a data storage device at any time for security purposes to ensure that the firmware on the storage device has not been tampered with.
