You're unlikely to 'break it more', it's probably the/an actuator arm that's fucked (or more accurately, stuck). But it could also be the pcb is shorted somewhere. Or the partition table is so messed up it literally doesn't know where to start.
I've had some luck with getting dead drives to 'randomly' restart after repeated efforts over several days (i.e. try it ten times in a row, leave it). If you do get it to spin up, you should treat it as the likely last chance you'll ever have to recover the data.
