Abstract
A removable digital data storage device has a programmable memory controller, a data storage medium and a data destruction means. The memory controller is encoded with a firmware program to provide a computer device driver interface, wherein the firmware program further configures the memory controller to secure data on the medium by querying for a hardware code in response to a data operation request by a computer through the interface and either granting access in response to a hardware code input or, independent of an operational status of the requesting computer, directly instructing the data destruction means to render data residing on the data storage medium unreadable in response to a failure to receive the first hardware code input through the interface.
