Abstract:
An electronic system includes a framework, data storage circuitry and a controller. The framework includes multiple device slots. The data storage circuitry is arranged to access storage devices installed in the framework. The controller is arranged to receive a current storage device identifier in response to installation of a storage device into a particular device slot of the framework, and perform an electronic storage device location assessment operation based on the current storage device identifier. The controller is further arranged to provide a control signal in response to performing the electronic storage device location assessment operation. The control signal selectively (i) permits the data storage circuitry to overwrite the storage device while the storage device resides in the particular device slot, and (ii) prevents the data storage circuitry from overwriting of the storage device while the storage device resides in the particular device slot.
