1. An improved locking device for preventing unauthorized access to computer disk drives that have an external latch that has an open and a closed position, said closed position being designed to prevent entry or exit of standard disks appropriate to the drive;

  • said device comprising;

    a) a slide plate to be inserted into the drive when the latch is in the open position;

    said slide plate being designed so that when the latch is in the closed position the slide plate is prevented from complete removal from the drive in substantially the same way as a standard disk appropriate to the drive is prevented;

    b) flanges on the edge of the slide plate opposite to the edge that is inserted into the drive, the spaces between flanges being designed to allow the latch to move into the closed position when the slide plate is at its maximum insertion, and being also designed so that when the slide plate is thereafter moved out of the drive an appropriate amount certain flanges block the movement of the latch such that it cannot return to the open position; and

    c) a means of locking the slide plate into said position in which flanges block the movement of the latch.
