@matigo If the 80MB in question is a Segate ST-4096 full height, a fair amount as most of those developed "marbles and gerbils in a blender syndrome"
The head actuator would go ape and fling the heads all over the place thus making a racket that sounded just like gerbils and marbles in a blender. Then it became a heavy paperweight. I still have a functional one in an attic in WV
