A network-attached storage system, comprising: at least one removable storage medium, the at least one removable storage media including a radio-frequency receiver and memory for storage and associated circuitry for erasing or disabling access to the memory upon receipt of an appropriate signal via the radio-frequency receiver; at least one socket (130 - 137) for receiving a respective one of the at least one removable storage media associated with the socket (130 -137); at least one host controller (140 - 147) coupled to a respective one of the at least one socket (130 - 137), wherein each of the at least one host controller (140 - 147) determines when the respective one of the at least one removable storage media has been installed in or removed from the respective socket (130 - 137); a network interface controller (111 - 114) for coupling to an external network; a radio-frequency transmitter; and a controller coupled to each of the at least one sockets (130 - 137) via the respective one of the at least one host controllers (140 - 147) and to the network interface controller (111 - 114), the controller for reading information from and writing information to the removable storage medium when installed in the socket (130 - 137) in response to read and write commands received via the network interface controller (111 - 114), the controller providing responses via the network interface controller (111 - 114) to the received commands based on the information read from or written to the removable storage medium, wherein the controller receives signals from each of the at least one host controllers (140 - 147) indicating when the respective one of the at least one removable storage media has been has been installed in or removed from the respective socket (130 - 137), wherein the controller determines, when one of the at least one removable storage media has been has been removed from the respective socket (130 - 137), that the removal was unauthorized and the controller sends a signal to the radio-frequency transmitter for transmission to the radio-frequency receiver in the removed one of the at least one removable storage media to cause the memory in the removed one of the at least one removable storage media to be erased or cause access to the removed one of the at least one removable storage media to be disabled. at least one removable storage medium, the at least one removable storage media including a radio-frequency receiver and memory for storage and associated circuitry for erasing or disabling access to the memory upon receipt of an appropriate signal via the radio-frequency receiver; at least one socket (130 - 137) for receiving a respective one of the at least one removable storage media associated with the socket (130 -137); at least one host controller (140 - 147) coupled to a respective one of the at least one socket (130 - 137), wherein each of the at least one host controller (140 - 147) determines when the respective one of the at least one removable storage media has been installed in or removed from the respective socket (130 - 137); a network interface controller (111 - 114) for coupling to an external network; a radio-frequency transmitter; and a controller coupled to each of the at least one sockets (130 - 137) via the respective one of the at least one host controllers (140 - 147) and to the network interface controller (111 - 114), the controller for reading information from and writing information to the removable storage medium when installed in the socket (130 - 137) in response to read and write commands received via the network interface controller (111 - 114), the controller providing responses via the network interface controller (111 - 114) to the received commands based on the information read from or written to the removable storage medium, wherein the controller receives signals from each of the at least one host controllers (140 - 147) indicating when the respective one of the at least one removable storage media has been has been installed in or removed from the respective socket (130 - 137), wherein the controller determines, when one of the at least one removable storage media has been has been removed from the respective socket (130 - 137), that the removal was unauthorized and the controller sends a signal to the radio-frequency transmitter for transmission to the radio-frequency receiver in the removed one of the at least one removable storage media to cause the memory in the removed one of the at least one removable storage media to be erased or cause access to the removed one of the at least one removable storage media to be disabled.
