is my MBP HD faulty? movies freezing when MBP moved/shaken...

[volcom883]

hi,
i dont know this used to happen before but ive noticed it a couple of times recently that every time i moved my MBP when putting it on another surface like a bed or sofa [obviously the HD shakes a bit] and the movie thats playing freezes for 1-2 seconds.

can you do this test for me:
put the MBP on your lap, play a movie, lift the left side about half an inch then drop it. mine freezes..

is that normal?

It might be the Sudden Motion Sensor in action.

What's with the sudden rush of posts related to sudden motion sensor. Just read this to help you understand how the process works:

Basically, once SMS is active it moves the heads of your HD out of the way to avoid data loss; that's the reason your movie freezes for few seconds because the write/read operation is halted briefly. HTH...

Well others already answered why its doing it but


STOP SHAKING YOUR LAPTOP! Its seriously bad for it.

I think it's a flaw. The sensor is way too sensitive. You can't watch movies on the road because a small bump will park the drive. Heck, I can bump my desk and I can hear it park.

Same here. My MBP has the Apple-issued 7200 RPM drive in it, and I swear I can glare at it and it parks itself.

this kind of thing makes me really wish I could afford to overpay for an SSD.

If you find it too sensitive, just disable it... I've used laptops for years without SMS and never had HD failure, while the "stationary" desktop had 3 HDs failed so far in it...

As usual reset your PRAM and SMC first.

It would have saved me an embarrassing trip to the Apple store if I had.
