1. A secured external computer storage device attached to a portable computer, comprising:

  • a portable hard drive,a circuit board onto which is mounted a dual-function component consisting of a magnetosensitive random access memory (MRAM) and a microcontroller,a wireless transceiver capable of bidirectional communications between the microcontroller and a processor hosting a Web site, where the Web site is configured to perform a method for securing the portable hard drive,a GPS capable of identifying whether hardware components of the storage device are physically located in a permitted building, andfirmware stored in the MRAM comprising instructions for securing the portable hard drive, anda switching mechanism that controls distribution of power to components of the storage device, where the switching mechanism is capable of only three disabling operations;

    disabling power to only the circuit board, disabling power only to all components of the storage device other than the circuit board, and disabling power to all components of the storage device, the method comprising;

    the processor of the Web site receiving, through the transceiver, a notification that the GPS has determined that the portable hard drive is no longer in the permitted building;

    the processor, in response to the receiving, notifying a user of the portable computer that the portable hard drive is no longer in the permitted building; and

    the processor, in response to determining that the portable hard drive remains outside the permitted building after the notifying, instructing the microcontroller to perform the following sequence of operations;

    disabling power, by means of the switching mechanism, to the hard drive but not to the dual-function component;

    directing the portable computer to reboot and request a security code; and

    , upon a failure to receive a desired security code, removing the device from a BIOS of the portable computer without restoring power to the portable hard drive and without purging data from the portable hard drive.
