    Ok guys,

    I got it and I want to show this information with you.

    I contacted bot Western Digital and Apple.

    The WD5000BEKT (aka Scorpio Black 500GB) does have the free fall sensor, like all the others scorpio blacks 500 GB and 750GB. The scorpio blues do not have the free fall sensor.

    In order to make it works inside the HDD bay of our beloved MBPs we have to disable Sudden Motion Sensor (SMS).

    My question is: does this procedure (disabling SMS under mac os x) disables SMS under win 7/bootcamp, too?

    Have some people experienced some problems with this WD model?

    I'm confident it would not.

    They are two separate operating systems. One very rarely affects the other.

    As you say, there is an SMS built in the HDD itself.

    The Apple's technician said that under bootcamp the SMS SHOULD not work (so nothing for sure), for this reason the better proof we can have is from someone who is using this HDD inside his MBP

    From browsing around Western Digitals website it would appear that black scorpio models ending in BJKT have the free fall sensor, drives ending in BEKT DO NOT.

    I am using the wd5000bekt in my 2011 i3 with great success. No noise, heat, power drain or SMS issues so far.

    Right now, I have a HD scorpio black 750 Gb WD7500BPKT connected thought a sata to usb adapter to my MBP '10. I am cloning my hdd (scorpio black 320 Gb BEKT) to replace it with the 750 Gb.

    As you can see, the scorpio black 750Gb has a BPKT code, so does it have the free fall sensor or not?

    Should I disable sudden motion sensor in OS X?

    Please help. Thanks.

    I ran the Scorpio Black 320GB drive with the sensor in my Early 2009 MBP with no conflict whatsoever (SMS in the default enabled setting).

    I was following an earlier thread on the Scorpios and called the local WD importer.

    Only the BJKT model (320GB) had the free-fall-sensor. It is not produced anymore, nobody knows why. I am assuming that the free-fall-sensor tech is superseded by the new techs, see below.

    Both Black and Blue are using Shockguard and SecurePark technology (no free-fall sensor) and their differences are mainly speed (7200 v 5400 rpm) and noise (28 v 22 dBA for 750GB models).

    Also, the 1TB Blue is 12.5mm height, not 9.5mm like all other models, make sure it fits into your laptops/optibays.

    So definitely there's no need to disable SMS, right?

    As you can see we have conflicting information in this thread...

    No, not unless you want to install the smaller, older, BJKT model.
    BEKT and BPKT do have motion sensor but not that older one (by the name: free fall sensor) that needed disabling.

    Thanks.

    I already swapped the hard disks and I can confirm it's running just fine with SMS on.

    It's nothing short of amazing how easy it is to upgrade a MBP hard disk; just run Carbon Copy Cloner in the background, swap hard disks (5 minutes task) and boot from your new shiny and big hard drive... :cool:

    SSD's are amazing, but I do need the space.

    As far as I know BPKT and BEKT models do not have free fall sensors.

    Would probably be easy to check on www.wdc.com

    Hi! I'm thinking of installing the same WD7500BPKT on my MacBook Pro 15" Late 2011. Would you still recommend it based on your experience with it since this post? Have you hade any problems with it since?

    Thank you!

    Yes, actually I have a '11 17" MBP, and the Scorpio Black is still going strong as my main storage disk on optibay.

    No problems at all.

    I have question. Do I still need a HDD that has SMS if it is just sitting on a desk? My room where the macbook is kept is on the second floor and the apartment is old and sometimes when my 5 year old kid is running you can really feel the vibration of the floor. Do I need an SMS?
