ABSTRACT:
A security device is disclosed for a computer having a controller, a main storage device and a drive for an auxiliary storage device, the security device comprises a first mechanism for electronically connecting the computer controller to the auxiliary storage device drive, a second mechanism operatively connected to the first mechanism for selectively blocking signals passing between the computer controller and the auxiliary storage device drive so that the drive is at least partially disabled, and the second mechanism including a lock which is selectively actuatable by the operator independently of operating the computer for enabling and disabling the second mechanism. Additionally, the security device also preferably includes a communication driver which may be loaded into the computer for cooperating with the computer controller to operatively partition a main storage device of the computer into a safe storage area storing pre-existing programs and data, and a working storage area for temporarily storing new data input by a user, and the second mechanism may be actuated so as to either totally disable the auxiliary storage device drive or to partially disable the auxiliary storage device drive such that it may only input data to and retrieve data from the working storage area of the partitioned main storage device.
