Driving and watching a DVD - sudden motion sensor

Just out of curiousity, I was on a road trip and brought the MBP with and watched a DVD. The ride was somewhat bumpy. My question is do you think the hard drive is being used slightly during the playback of the DVD? AND does this pose any issue or possible damage from the "Sudden Motion Sensor" working indefinitely?
What do you guys think

I would doubt it. The sudden motion sensor is only going to engage if there is a major change in G-forces on that machine -- i.e. it flies out of a seat. The normal vibrations associated with driving shouldn't activate the sensor and your machine ought to handle them... Of course, there is the issue of whether or not you ought to be watching movies whilst driving, but that's another matter altogether...

  • Sudden Motion Sensor on OSX 10.4.6 (iBook/PowerBook  G4)

    cheers!
    according to http://docs.info.apple.com/article.html?artnum=303178, there is a problem with the sudden motion sensor on my ibook g4 14'.
    my questions are:
    1. is the sms really not working or is it just not showing up in the system profiler?
    2. what should i do to bring sms (back?)to work? install a macosx-version prior to 10.4.3?
    3. did the sms on my ibook ever work? bought it with 10.4.3 on it.
    thanks for the answers.

    Hi Mmkay,
    Welcome to Apple Discussions
    I am sorry, but just to make sure; Does the Sudden Motion Sensor not show up in System Profile (Getting Information About Your Computer (System Profiler)). In System Profiler > click on the Hardware tab > Look in the main window and you should seen Sudden Motion Sensor below Serial Number. Does it say State: Enabled? If it doesn't show up, bring it to your local Apple Store. I don't think that reinstalling the system software will make a difference.

  • 10.6.8 update and sudden motion sensor

    I have MBP 8,1, 2011 base model i5. Since i updated to 10.6.8 it seems like sudden motion sensor got a lot more sensitive. Never seen it work before, now if i lift the mbp from desk even i can hear the hdd clicking home. I have disabled the sensor and it stops even i move the computer around very fast. So it is not just the drive doing, sensor is triggering that.
    I was wondering if anyone knows if sensivity of this sensor changed on last mac os update? or if anyone else noticed it too?
    Thx
    Ozzy

    Hi Ozzy,
    I have not noticed any difference on my MBP.
    You can try an SMC Reset, which can resolve SMS issues: http://support.apple.com/kb/HT3964

  • Powerbook and sudden motion Sensor??

    hi everyone,
    I have a Powerbook 17" 1.33ghz does anyone know if it has the sudden motion sensor fitted to it and if not can it be done?
    Thanks
    Danny

    Danny--
    Your PowerBook won't have the sudden motion sensor, it's only on the last two G4 17" models, both featuring 1.67GHz processors. I really doubt it would be possible to add it, either. It's pretty closely tied to the hardware and would require too many changes to your PowerBook.

  • Sudden Motion Sensor disabled constantly after Leopard install and upgrade

    Hello,
    After I upgraded Tiger to Leopard my Sudden Motion Sensor is constantly disabled. I have tried alot now, including a complete reinstall of Leopard (which now looks like a waste of time, since it didnt help at all).
    I called Apple support yesterday and the guy i talked to had me doin alot of stuff - botting with a key combination, creating a new account, and now after his advise doing a hardware test and if that didnt work I should try reinstalling Leopard.
    All done, nothing changed. It still shows;
    Sudden Motion Sensor:
    Status: Slået fra (danish, properly says disabled in english)
    AMSTracker and all other software that uses SMS doesn't react on anything.
    I haven't tried installing Tiger again since I have to use this laptop on work by Monday and haven't got the time tomorrow to install it again.
    Has anyone experienced this, and anyone that knows a way to get SMS working again?
    I use my laptop a lot when I ride with trains, but with SMS not working I feel kinda unsecure - dont wanna have a headcrash on the harddrive or something like that :-/

    I contacted Apple today. My last call was apperently not registered in the system (sometimes the calls gets removed I was told... Ehm, what?).
    The lady I talked to had to contact a technical department (and wait in a queue... Exactly as I had in 40 minuttes just to get through to her). After waiting on that, she returned to me and said that it apparently is a hardware failure so I have to bring my MB into a Service Provider (Humac here in Denmark).
    I got a case number from her and is able to call Humac and ask them to get the spare parts home for that case number. When they get the spare parts, they should then call me and tell me. Afterwards I can bring the MB into the store when ever I got the time (as I use it work related, so I can't be without it for a day).
    That is pretty much my 'fix'. Haven't contacted Humac yet, but will do that tomorrow. Gotta get some sleep now.
    And yes, SeisMac and Neverball too is fun

  • Sudden Motion Sensor and WD Scorpio drives

    I'm researching the 13-inch MacBook pro. I stumbled on this thread: http://discussions.apple.com/thread.jspa?threadID=683913 which says that the Sudden Motion Sensor in Apple portables have issues with kernel panics when you use Western Digital's Scorpio line of hard drives. I was wondering:
    - Is there a way you can disable SMS in System Preferences?
    - If I get WD's Scorpio drive without their implementation of SMS ("free-fall sensor"), will Apple's SMS take over without KPs? Or do I have to use a stock drive?
    Thanks!

    http://support.apple.com/kb/HT1934
    Also, the application Cocktail can disable SMS by disabling it and without venturing into the Terminal.

  • Sudden Motion Sensor and a new hard drive?

    I was just wondering if the Sudden Motion Sensor will still work with a non-Apple hard drive.
    If so,
    I am also looking for a 160GB hard drive replacement for the Macbook. Something fast, reliable, quite, and most important, good quality. And low power consumption, if possible
    P.S. I am also looking for 2GB RAM, with the same qualities.
    Thanks.

    Nick,
    oddly enough there have been reports of the SMS not working properly with some Western Digital drives, which have their own SMS system as well. I happen to have a 120G WD Scorpio, but haven't seen the problem myself yet. I'm sure OWC will replace it without problems if it crops up though-one advantage to dealing with a Mac specific dealer

    Is there a compatibility issue when choosing a replacement hard drive if the Powerbook as the Sudden Motion Sensor?

    No, the sensor is not integrated into the hard drive.

  • Sudden Motion Sensor crash in MBP with SSD

    Hi.  I replaced my 2011 17" MBP's internal HD with one, then another SSD from OWC, going from 240 to 480.
    As indicated in OWC's instructions, the Sudden Motion Sensor no longer applies and should be disabled with this command from the terminal:
    $ sudo pmset -a sms 0
    And using this command, we can see that the SMS is off:
    $ sudo pmset -g
    Active Profiles:
    Battery Power                    -1
    AC Power                    -1*
    Currently in use:
    womp                    1
    halfdim          1
    sms                    0
    What happens all too often though is that my Mac issues an SMS crash while asleep if I am driving home and hit a bump in my car.  Just Monday, I was driving with my Mac open and on, the car hit a bump and I got to watch the Gray Screen of Death as the Mac issued a kernel panic from the Sudden Motion Sensor. 
    But it's off. 
    FYI, I turned it off to try and stop this behaviour

    Don Montalvo was preventing the crashes by turning off SMS.  However, replacing bad RAM was the ultimate solution.

  • Logic 9 sudden motion sensor error.

    Hi Guys,
    my rig often gives me the "system overload, sudden motion sensor" error during playback, its driving me nuts, the thing that really gets me is that its a mac pro, booting off an SDD, audio is running off a fast drive and the whole lot is in a shockmounted flightcase, i have no idea how the sudden motion sensor could be doing anything at all.
    does it have something to do with the 2.5" SSD the rig boots off?

    Hi - I am experiencing this error as well. I believe the issue is due to Logic Pro not quite ready for Lion. I just bought a new iMac 2.5 GHz 4GB RAM.  Got it to run Logic, and found 9.1.1 doesn't even run on Lion. After upgrading to 9.1.5 the first thing I tried to do was open the demo projects from The Killers and Lilly Allen, to see what this software is all about. Logic hangs somewhere while loading all of the tracks/software instruments, and needs to be Force Quit. The Santigold project loads but it gives me this error about a minute into playing it:
    Disk is too slow or system overload
    (-10010)
    The sudden motion sensor may have parked the hard drive head, or the disk performance is not sufficient to read or write all audio tracks, or the system was not able to process all data in time.
    I do not yet have an external drive and am not sure if running project files off a fast external (as opposed to the system drive running Logic) would resolve the issue. But I notice the error is broad and basically multi-purpose, not necessarily stating that your hard drive has parked for sure, rather that disc/system performance couldn't keep up. I haven't duplicated the error when playing my own projects, with less tracks/software instruments. I think that there may be a threshold where you can just push logic too far for Lion interoperability on this 9.1.5 release. Hoping for a new release soon! Good Luck!

  • Hard drive upgrade on 13" MBP sudden motion sensor compatibility

    Hello,
    I'm planning on upgrading the hard drive in my 13" MBP (aluminium unibody) and I've read a lot of posts regarding the sudden motion sensor conflicts with OS X 10.6.2. I'd like to know if the Western Digital 500GB Scorpio Blue here (http://www.dabs.com/products/western-digital-500gb-scorpio-blue-5400rpm-sata-300 -8mb-58P6.html) would suffer from the conflict (I'm not sure if "Shock Guard" = sudden motion sensor). I don't know if its a simple yes/no or whether its drive / mac specific.
    If it would be a problem does anyone have a suggestion for a guaranteed compatible 500Gb hard drive (5400 rpm is fine)?
    Any thoughts are much appreciated, thanks for your help!

    Western Digital Lists their drive features as:
    * IntelliSeek™ - IntelliSeek technology calculates optimum seek speeds to lower power consumption, noise and vibration.
    * SecurePark™ - WD's SecurePark technology parks the recording heads off the disk surface during spin up, spin down and when the drive is off. This ensures the recording head never touches the disk surface resulting in improved long term reliability due to less head wear, and improved shock tolerance.
    * ShockGuard™ - WD's ShockGuard technology protects the drive mechanics and platter surfaces from shocks during shipping and handling and in daily operation.
    * Free-fall Sensor - As an added layer of protection, if the drive (or the system it's in) is dropped while in use, WD's free-fall sensor detects that the drive is falling and, in less than 200 milliseconds, parks the head off the disks to help prevent damage and data loss.
    * WhisperDrive™ - WD's exclusive WhisperDrive technology combines state-of-the-art seeking algorithms that result in one of the quietest 2.5-inch drives on the market.
    The Free Fall Sensor is the equivalent of the Sudden Motion Sensor. Looking at the specs for the drive you linked to... they list the following features:
    Shock Guard, WhisperDrive, SecurePark
    As they do not list Free Fall Sensor, I'm guessing this model does not have one so it should not conflict with the internal Sudden Motion Sensor in your MacBook.

  • Second Hard Drive, Sudden Motion Sensor

    Back in the fall I put a SSD in my 2007 MacBook Pro. It's working perfectly. I found the "OptiBay" product, which basically replaces your optical drive with an adapter for another hard drive. I haven't received it yet, but when I do I plan on installing it with a traditional hard drive. My question regards the sudden motion sensor (SMS). I disabled it because it's not needed for the SSD, but I was planning on re-enabling it for my secondary that I will be installing. I'm still going to boot off the SSD, though. Is there a way, or terminal code, to assign the SMS to a certain disk? I'm assuming it will just disable the root drive in the event of "sudden motion," but would this affect a secondary drive?
    I'd love for there to be an option to change the identifier, from disk0s2 to disk0s3, but I have a feeling it isn't possible or would be infinitely more difficult... thanks.

    Most drives are available with the equivalent of an internal SMS. You just have to check the specs. Drive manufacturers often offer two versions of their drives... one with and one without a SMS. If you get a drive with the SMS built in, you can just leave the MacBook's internal one disabled.
    Here is an example of one of the most popular drives:
    http://www.seagate.com/www/en-us/products/laptops/momentus/momentus5400.6g/
    Seagate's SMS technology is referred to as G-Force. Note the product number: 5400.6_g. The "g" denotes the drive has a "G-Force" sensor.

    As Apple say at http://support.apple.com/kb/ht4103
    When typing the user's password after the "Password:" prompt appears, you will not see anything appear in the Terminal window. Just type in the password and press Return. If the password is entered incorrectly, you will see the message "Sorry, try again" and be given another chance to enter the password correctly.

  • Why would I get a Sudden Motion Sensor error on a Mac Pro (not a laptop)??

    Get this error all the time since upgrading to Logic 9.1.4.  Thing is, I have a Mac Pro, not a laptop.
    Apple sends me to this page:
    http://support.apple.com/kb/HT1934
    Should I disable sudden motion sensor?  Seems silly.  I am recording woth headphones, there's no movement from the computer.   And again, didn't have this error for 3 years and suddenly I get it after upgrading to 9.1.4?

    9.1.4 seems a bit shaky...
    That said, you might try disabling "Sleep" for the drive.
    As I recall, it's a generic error meaning the computer either isn't getting a response from the drive or that it can't pull data off fast enough.

  • Sudden Motion Sensor not working after upgrade to WD5000BEKT HDD

    Hi everyone, I just upgraded the hard drive on my Macbook Pro (2010) and I am very pleased with the performance of this 7200rpm drive, I have seen reads around 105MB/s and a pretty good boot time at 23s. But I used to be able to hear the hard drive stop when I moved the computer around before due to the Sudden Motion Sensor technology and since I have the new hard drive in it doesn't seem to work anymore. I have tried switching SMS off and on and it didn't change anything, also the drive is a Western Digital Scorpio Black without Free Fall sensor (I took that version on purpose so it wouldn't conflict with the SMS). Do you have any ideas on how to make it work again? Because I really like this feature on my Mac (I have dropped a laptop before so just in case it happens again). Thanks a lot for your help.
    Scott

    For future reference, here are a couple of kb articles on the sudden motion sensor:
    http://support.apple.com/kb/HT1935
    http://support.apple.com/kb/HT1934
    As has been said, Apple's Sudden Motion Sensor is not actually built into the hard drive. In fact, some hard drives with their own version of a sudden motion sensor like Seagate's G-Force Protection actually will set up a conflict with Apple's Sudden Motion Sensor.
    I installed the same WD in my Mac as you did, and I hope you enjoy it as much as I have been enjoying mine.
