Device controller and method implement time-based sector level safety

摘要

A device controller interfaced between an electronic processing device and a sector-based data storage device, includes a processor connected to a clock, and a computer memory having a control list stored therein. A control list includes a security feature entry having a target sector range, time data associated with the target sector range, and at least one security response associated with the target sector range. The processor determines, based at least in part on interrogation of the control list and a clock time, the time data of the entry conflicts with the clock time, and executes the at least one security response.
