    I've been getting the irritating head-parking sounds coming from the HDD on my 13" Macbook Pro. I've tried hdapm which stops the heads parking every 15 seconds or so, and correspondingly stops the load cycle count from increasing.

    My question is this: does this disable the Sudden Motion Sensor? I saw a post on the Apple discussion forums that vaguely suggested this might be the case, but without a clear conclusion one way or the other. I want to make sure that the sensor is still enabled when the APM level on the hard drive is set to "max" but I'm not about to pick up my Macbook and start waving it around to see if it works. :)
