A data storage device is disclosed comprising a non-volatile memory and control circuitry operable to evaluate a physical feature of the data storage device, wherein the physical feature is physically alterable by a user. When the physical feature is in a first state, host access to first secure data stored in the non-volatile memory is enabled, and when the physical feature is in a second state, the host access to the first secure data is disabled and host access to second data stored in the non-volatile memory is enabled.
