Logic 9 sudden motion sensor error.

" Error synchronisation " ?

Mac Pro as in Desktop Tower? The only motion sensor on that machine would be the one on the audio drive. This is being used for Live shows?

The audio drive is formatted Mac OSX Extended Journaling OFF, correct?

If it's being used for Live shows it's conceivable that loud bass frequencies can bounce the drive head.

Other possibilities: The the sudden motion sensor error is simply referencing that it can't get the data fast enough or the drive is not responding.

System Preferences/Energy Saver... Make sure the system sleep is set to Never and that -all- drives are never put to sleep.

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!

Whoops I just noticed you are on Snow Leopard. Still I think this is an issue with Logic and that your hard drive is OK...

and pancentre, yes it is a 8 core mac pro, its never happened during a show oddly enough, its only ever happened when i've been remixing old soundchecks ect, but its frequent, i'm used to the sytem overload message, but this one if diffrent, it links me to an apple support site for macintosh portables, which confuses me no end, ive never seen it on my real portable.......

The audio drive is seperate and in bay 2, and is formatted mac os jornalled (not case sens) and it is set to never sleep to prevent it falling asleep if someone left it mixing a show to long.

thanks for the replies, im gonna need to keep testing it.

Did the motion sensor message start after the installation of the ssd?

Does the ssd come with any kind of configuration utility?

The error could be caused by the ssd if it goes into a standby mode.

Since mixing a soundcheck would use more memory as plugins are used/swapped and mixing by it's nature uses more memory the OS will be writing swap files to the ssd, if the ssd were to go into a standby mode the error might occur.

Jack...

Also.. the next time your audio drive is empty (ha!) or you install a new one, format it Mac OS extended journaling OFF. Journaling an audio drive is a waste of resources and will not save any data in the advent of a system/disk crash.
