WiebeTech USB 3 DriveDock A power status LED verifies that the unit is switched on or off. Another LED confirms that the Dock is accessing the drive, and a third confirms that a valid USB connection is established. Just connect the drive to the Dock, plug in power and attach a USB cable to a host computer. That's all it takes. For more protection to the drive, a mounting plate (included) can be screwed onto the bottom of the drive to protect the drive's circuitry. Need to access a non-standard drive? Use one of WiebeTech's own Combo Adapters to access 1.8" drives, notebook drives, drives found in iPods... almost any spinning disk. Combo Adapters work with many of our DriveDocks, including USB DriveDock v5.
