I'm pretty sure you can trash a drum if you hit it on the curved face of its
outer _diameter_ instead of the perimeter of the flat drum face.  Because
you're trying to break the rust bond between the inside face of the drum
and the flat face of the hub, you need to "rock" the drum out of the
plane of the flat face.  Hitting the curved outer diameter of the drum
sure wouldn't accomplish this very readily until you hit the drum with
_lots_ of force.  Sounds like that's what they did.

Maybe there's some sort of puller you can use on these drums (not the
hub, the drum) but it seems improbable: the brake backing plate prevents
you from getting a grip on the edge of the drum itself, so the only way
to "attach" the puller to the drum would be with some sort of tightened
band (like a huge hose clamp) that you would wrap around the drum itself.
