an RFID device provided in said host computing device and provided in other computing devices for receiving and sending RFID signal;

means for automatically detecting a triggering event associated with said host computing device, said trigger event comprising detection of a physical removal of said storage device from said host computing device, said detecting means initiating, without manual intervention, automatic purging of content of said data storage device by automatically generating, via said RFID device, an RFID activation signal including an identification code representing an instruction to purge contents of said data storage device contents; said RFID device allows detection of a remote triggering event via wireless RF signal;

control means responsive to said RFID activation for invoking logic to initiate a physical purge of contents of said data storage device, said control means including a purge BIOS module executing logic stored at a physical level of said storage device to ensure a physical delete of said storage device contents; and

said RFID device at said host computer generating further RFID activation signals for communication to said other computer devices via said RFID device of said host computing device, said further RFID activation signals for receipt by said other computing devices to initiate purging of stored contents at said other computing devices; and,

wherein said data storage device and said other computing devices each comprise a power supply device operable for powering said RFID device and said purge BIOS module such that said physical purge of data storage device contents is performed when said storage device is removed from said host computing device or, is performed when said host computing device is not powered.
