1. A data storage device comprising: a printed circuit board including a plurality of mounted chips each comprising internal circuitry; a non-volatile memory; and control circuitry operable to: evaluate a physical feature of one of the chips, wherein the physical feature is physically alterable by a user; when the physical feature is in a first state. enable host access to first secure data stored in the non-volatile memory; and when the physical feature is in a second state, disable the host access to the first secure data and enable host access to second data stored in the non-volatile memory, wherein the physical feature comprises a modifiable package of one of the chips, and modifying the package of one of the chips destroys at least part of the internal circuitry of the chip.
