Cannot see status of sudden motion sensor ( imac 5,1 )

Im using logic 9 and ive fitted a new hard drive to my imac i keep getting a warning notice in logic that the sudden motion sensor may be parked however when i open terminal to try and determine the status of the sensor eg: to turn it off i cannot see the sms status option so i do not know if the sensor is on or even if i have one at all. can anybody help me with this thanks.

iMacs don't have a Sudden Motion Sensor.
Apple uses a Sudden Motion Sensor only in their portable Macs Apple Portables: About the Sudden Motion Sensor and Apple Portables: Advanced tips for Sudden Motion Sensor
Plus 3.5" harddisks used/fitted in an iMac don't have Sudden Motion Sensors to my knowledge.
To be sure check the product details of the harddisk you fitted in your iMac.

Sudden motion sensor is not showing up on terminal. how do I switch it off on my imac

I have an imac with os 10.9.2 and logic pro 9.1.8 .. i am getting a sudden motion sensor error for a very small track with 4 plugins.. this error never shows up on FCP or any other heavy duty software. So I wanted to switch the sudden motion off but can't find it in the terminal while typing sudo pmset -g .. so how do i find it and how do i switch it off.

Hi
In that case you are going to have to give us some more information:
Just one project or all projects?
Does it still do it if you bypass all the plugins?
What buffer size are you running at?
If audio tracks, are you recording/playing back from the System Drive?
What Sample rate/bit depth?

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!

followed direction but it would not let me enter password. No keys will work on keypad when trying

It's normal to see no characters on screen when entering the password for sudo - they're still recognised.
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.

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.

Drive Upgrade: Sudden Motion Sensor & SMART

Greetings,
I have a couple of technical questions regarding a Hitachi HD upgrade I am planning. I purchased the 5K500.B from Other World Computing (OWC) and had some concerns with the Apple Drive Utility when I went to format it.
I also purchased an external enclosure that I can mount my old drive in after I replace it. When I went to format the new drive (in the external enclosure) with Drive Utility, I noticed some differences between the old drive and the new drive. The original drive is a Hitachi 200 GB 7200 RPM which Apple supplied as an option. I will list my MacBook Pro information after this section. My questions are:
1) SMART status reads "Unsupported" on the new drive and "Verified" on the old drive. OWC said this is because SMART only works on internal drives and SMART will work after I install the new drive. I just want to check the accuracy of this statement.
2) My MacBook Pro has a Sudden Motion Sensor for drop protection. Is that built into the laptop or the hard drive? Will Apple's drop protection work with the new drive?
3) Is the 5K500.B really a direct replacement with all the functionality of the original drive.

I read in one of your posts that the sudden motion sensor can be easily disabled. Could you please tell me how?
I can be online, or not, and the crazy spinning colored disc starts to spin, then if I pick it up and set it back down usually it stops and the macbook (4,1) continues with it's work. I guess that it is the sudden motion sensor although I could be wrong...Just seems strange that it normally stops when i pick it up, tap it, gently, etc.
Could you please advise? It shows enabled in 'about this mac' but I can't find anyplace to dis-able it.
It's almost impossible to stream video, although that may be from something else.

Is this a problem with the Sudden Motion Sensor or the HDD?

I have a MacBook that I purchased in Septemberof this year, and for a while I have been having a problem with the HDD. I understand that there is a Sudden Motion Sensor that parks the hard disk when the computer is moved suddenly, but every hour or so I can hear the HDD make a single loud click for seemingly no reason at all. The computer can be sitting on my desk with no applications running and this will still happen. This is not really much of a problem other than the annoying noise, but if I am playing music or a video from the HDD it will skip when it does this. I have disabled the SMS for now to see if it will make a difference, I am very careful with my devices so I do not fear that I will cause any HDD damage without the SMS, but I am not sure if it is a problem with the HDD or the SMS. Could anyone shed some light on this for me?

Well turns out disabling the SMS did nothing so I'm going to just take it in and hope it can be fixed.

Tilted sudden motion sensor in MacBook ?

I have download an application called "AMSVisualizer" to monitor the current reading of the sudden motion sensor. It will display a MacBook Pro/PowerBook and also display the readings of the sudden motion sensor in real time. When you move the laptop (even very slightly like typing the keyboard), it will sense and display some vibration. But my result is strange : I run the program when my MacBook is place flat on the desk and the "x" reading is flashing between 13-15, and the MacBook in the display showing that it is placing on a "non-horizontal" posture. I have to lift the left portion a little bit in order to make the "x" axis reading to 0.
Here is the photo as what I described above:
Tilt

Flat
http://copo.myphotos.cc/cody/photos/MacBook/MacBook_flat.jpg
Can some of the MacBook owner to test on this application to check your result ? The application could be downloaded here:
http://www.osxbook.com/software/sms/amsvisualizer/
Thanks!

Agreed with Jonas Hurtig. As you can see in my photo, I have to place the MacBook battery on the left side of the MacBook in order to have the reading looks normal. That is about 10-degrees tilt, there is no measurment needed for such situation if the desk is tilt like that, yor pens, desktop will slide off.....

Have you notice whether or not the motion sensor
works?
Apparently not (tested with iAlertU for example and with the software from http://www.kernelthread.com/software/ams/ams.html).
Yeah I'd probably take juhs10's advice and give Apple
a call if it's not working. It's a strange
occurrence. I would assume it's a software problem
but I'm not familiar enough with it to say for sure.
Thank you, I'll call Apple tomorrow to see with them.
Thank you for your help,
Gilles.

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 / Seagate Momentus 7200.4

All,
I am trying to check the Sudden motion sensor on my macbook pro unibody 2.8. Reason being i am a seagate momentus 7200.4 500gb (p/n ST9500420AS) drive and i want to make sure it is on. because I dont hear the drive park when I move it.
I go to terminal and do the following
When the command line appears, type sudo pmset -g and press Return.
Type in the administrator password when prompted and hit Return. This command queries the computer for the current setting of the Sudden Motion Sensor, which you can determine by locating the ams entry (in Mac OS X 10.3) or the sms entry (in Mac OS X 10.4 and 10.5) and looking to the right to determine its value. The default setting is "1" (turned on).
But it shows no setting. After I type the password it shows a blank line. How come I can not see this setting?

The SMS is not a part of the drive itself, it is a separate component normally located adjacent to the drive. It consists of a three-axis accelerometer that reports any motion of the computer to the Operating System. If it exceed a certain threshold, the O.S. causes the drive to park itself, presumably in anticipation to an impact. Some general purpose utilities, such as [MacPilot|http://www.koingosw.com/products/macpilot.php], allow you to enable or disable the SMS, there are also utilities specific for this.
An interesting application is [SeisMac|http://www.suitable.com/tools/seismac.html], which reads the info produced by the SMS and displays it as a graph, turning your Mac into a seismograph.
As for the operation of the system, I've found that if you close the lid on your portable and while it is updating the sleep image (before the LED starts pulsing), if you shake it, you will hear and feel the HDD coming to an emergency stop.

Sudden Motion Sensor - Where is it?

I recently bought a PowerBook G4 1.67 GHz 15" (M9677LL/A). Apple specs indicate this model is equipped w/ a "Sudden Motion Sensor" (SMS), however nowhere in its System Profiler can I find any reference to SMS enabled, disabled, or even existing. Do all 15" 1.67 GHz PowerBooks have the SMS feature? How should I investigate further?

Sudden motion sensor dissapears

Hi,
I have an issue with the sudden motion sensor on my computer.With the latest mac os x 10.4.10 the sensor always appears in the system profiler on warn starts (ie, when I reboot) but never on cold starts when I turn on the computer). I've tried with the original mac os disk that came with the PB with version 10.4.0 and the sensor always appears. I've tried with a retail mac os 10.4.6 mac os x installation disk and the sensor only appears with warm starts. I've updates 10.4.0 to 10.4.10 and I have the same problem, this upgrade done from system update and with the combo updater.
the only consequence is that widgets like Level don't work. Starting the computer takes like 1 second more and in the system.log log I get the error:

Apple has this kb article http://docs.info.apple.com/article.html?artnum=300781 but doesn't help much and this forum has reports from other people but with older versions of tiger and that got fix with version 10.4.3.
I've aldo used the AMSTracker program to report data from the sensor without problems (would that indicate the sensor works ok?)
Can anybody help me solve this error?
TIA

Update:
mac os x 10.4.0 to 10.4.7 to 10.4.8 to 10.4.9 to 10.4.10 works always.
mac os x 10.4.0 to 10.4.10 via combo update works only with hot starts.
In the post http://discussions.apple.com/thread.jspa?threadID=228309 they've found that in versions 10.4.0, 10.4.1 and 10.4.2 of mac os x the the motion sensors appears properly in the system profile but with update 10.4.3 Apple seems to break this until they've released version 10.4.7 which fixes it again.

Sudden Motion Sensor working strange in Unibody!

I got a macbook pro 15 recently and i was trying out the applications on the Net. I tried smacbook which works with the sudden motion sensor of the hard disk...
Also i tried liquidMac app.. But what i realised is, they both didnt work for me well..
when i lay down macbook through left side, the liquid must go to left for example, but nothing happens, actually when i move laptop through forward or backward they are moving..
And when i run SeisMac to see the axis of Sudden motion sensor my result is like this
Y-axis positive is left up, right down (clockwise rotation)
X-axis positive is front up, rear down
(Actually it must be reverse)
And suggestions?? Can it be broken or sth?
OR is there any way to play with this directions?
Should i send the laptop to service?

Are you saying the SMS does not respond in the same direction that you move it... or that certain axis do not function at all? The SMS is designed to protect your hard drive and nothing more. While developers have come out with some applications that can use it, there is functional benefit to which axis activates by which motion. The idea is that it detects "any" motion and locks the drive head to prevent damage. Now, if an axis is not functioning at all, you may want to look into that.

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

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.
