        Not that I know of. There was never a 'start_unit' command in the ST506 world.

        Mouse piss, like other forms of liquid contamination, is corrosive. The circuit board has likely been damaged, possibly on the inner layers (assuming it's more than a two-layer PCB, and I've yet to see one on any drive that was less than 4).

        Remove the board, and give it a thorough cleaning with 99% isopropanol. You may yet be able to restore it.

        Keep the peace(es).
