I think just HDD parking won't harm HDD, as my prev HDD was autoparking constantly (safe or powersave reasons). However in my case, I can hear a sound that is made by a vibration, it's like plates are slowing down and something is vibrating (arm?). It's kind the same with desktop PC, when your power is cut and your HDD are stopped too sudden. Thanks.
