Ok....you lost me. Haha. The hard drive is an external hdd and has a board that has the power input port a power button and is supposed to have the usb port this board plugs into the side of the hdd. The usb port broke off of the "power board".
Can you take the HDD out of the external enclosure and then carefully plug in a SATA cable and then connect the other end to an unused SATA port on the computer motherboard? The connection at the motherboard end will be secure. It is the HDD end that must be temporarily aligned and clamped together in some secure fashion temporarily.
