I had to disable the SMS on my 2010 Macbook Pro because it was triggering at the slightest motion of the machine. I'd have the system in my lap during normal use and just moving my leg slightly would trigger it, making an annoying clunk sound as the drive parks itself. Is there a way to re-enable the sensor, but at a lower sensitivity? I'd still like to be protected by it, but don't want it going off all the time. Not only is the sound annoying but the constant parking and unparking can't be good for the drive!
