An external docking station for a removable data storage unit, allowing it to communicate with a computer system via a standard interface connection, such as a USB connector. In one implementation, the present invention provides a docking station that, in a locked or closed mode, locks a removable data storage unit into place via a latch. In one implementation, the docking station includes a motorized, geared lever assembly that simultaneously unlocks and ejects the removable data storage unit from the docking station. In one implementation, a spring biases the latch to maintain the docking station in an open position for receipt of a removable data storage unit. In one implementation, after the user presses the eject button, the present invention delays ejection of the removable data storage unit until the hard disk drive is no longer in use, thereby preventing possible damage to the drive media and / or read-write heads.
