<p>A computing device (102) is coupled to a serial Advanced Technology Attachment (SATA) storage device (118) by an interface (200). A first partition of the external storage device is presented to the computing device as a Read Only Memory (108).The computing device is restricted from accessing one or more other secured partitions (110A-110N) of the external storage device until a valid identity authentication is provided giving unrestricted access to the other secured partition(s). In one example, in response to receiving a logon request from the computing device, an identity authentication process is initiated, using a process stored on the first partition (108). A process stored on a disk controller (112) of the interface receives an encryption key from the process stored on the first partition of the storage device, and the process stored on the disk controller uses the encryption key to decrypt the other partition(s) of the storage device (118).</p> |
