CoreAudio: Disk is too slow (Prepare) error message?

Hi,
In a Logic project I'm currenly working on, each time I open the file and press play for the first time, Logic hangs for 15 seconds or so and gives me this error message:
CoreAudio: Disk is too slow. (Prepare)
(-10001)
If I then stop, rewind and play again everything works fine. It only happens after this specific project is first opened and played.
Any ideas what this could be about? Disk is definitely not too slow. I get the same error if I start at a one track passage or bypass all effects and then play.
The file in question contains imported AIFF files, imported MP3 files as well 100 or so MIDI tracks.
Logic version is 7.2.1.
Thanks,
Maarten

It's in the energy saver preferences, uncheck spin down drive when idle thing.
HOWEVER, I posted this in another post, there is a bug where external firewire drives are still getting spun down with this checked off. I reported the bug to apple, they asked for more info, they said thanks, and last I checked the bug was still open, which tells me it wasn't reported before, and they're actually working on it.
So don't be surprised if unchecking the box doesn't fix it for your external drives.
The trick I use to get around it is simply double click the file on the external drive to open the song. That spins the drive up pretty good because you have to open a finder window which has to list all the folders etc...
hope this helps.

Disk is too slow (Record) error message

Hello there.
I've been using GB for 18 months now and have only few issues.
One issue I've had from time to time is an error message during recording. This in the past has meant that unless I'm paying attention to the screen, we can loose an awful lot of material.
It happened again this weekend and I managed to grab a screen shot.
The error message reads
"Garage Band
Disk is too slow. (Record)
(-10005)"
I'm using a 2.4Ghz Intel Core 2 Duo with 4GB Ram.
I'm recording to my internal Hard Drive which has over 90gig of free space.
I'm currently recording through an F-Control Firewire device, but I would also get this error when I used to use USB headsets.
Has anyone seen this error or have an idea whats causing this I'd love to know. Its always a pain having to be conscious that it could happen at any points, detracts from getting into the full flow of the conversation.
Thanks in advance
Matt

I'm using a 2.4Ghz Intel Core 2 Duo with 4GB Ram.
I'm recording to my internal Hard Drive which has over 90gig of free space.
All these data has nothing to do with your disk speed! This is measured in rpm, and an external disk with at least 7200 rpm might alleviate your problem.
What is your disk's speed? And how many tracks are you handling simultaneously?

I'm getting "the disk is too slow (prepare)" message

I'm getting "the disk is too slow (prepare)" message when trying to do literally anything in garageband right now, even with all other programs shut down, correct energy saver settings, and only one audio track in garageband.
Everything else on my macbook pro is running fine, iMovie, Safari, etc... so it seems like a garageband problem to me. I updated garageband, have reset computer multiple times, I don't know what else to do... it feels like garageband is keeping all of my recent projects open in the background at once, but when I check my windows, that is apparently not the case. Any help?

Anyone have any ideas to help?

CoreAudio: Disk is too slow

Have just switched over to MAC Pro Intel, a few years old. When press play in Garageband 3 get message "CoreAudio: Disk is too slow. (Prepare) (-10001)" This applies all previous Garageband 3 files and any newly created ones. I cannot play any of them. Can you tell me what this means and how I can fix? Thanks.

I looked at the Activity Monitor and didn't see anything using up resources. I saw disk writes peak out, but nothing to suggest why. I recorded track after track in the same project and finally after the 4th track, it started recording as long as I wanted without a problem. I'm going to chalk it up to disk fragmentation in that particular area.

GARAGE BAND disk is too slow. (prepare) (-10001)

Hi, Im trying to edit some mp3 files in separated tracks in GB on my NEW Macbook Air 2013 with 4gb ram and 128 flash drive, this files are between 170mb and 221 MB, so this message comes on: disk is too slow. (prepare) (-10001) garageband... what can i do? The files are MP3. What could be the problem? the 4gb of RAM? the 128gb ssd? Thanks!

How much free disk space do you have? Keep at least 10 GB disk space free for the operating system as working space, better more.
Try to lock all tracks that you are currently not using, while you are editing.
Close all other applications and reboot, before starting to work.
If the problem persists, you may have a problem with incompatible audio drivers. Then I'd test from a different user account, to check, if there is a general problem.

CoreAudio: Disk is too slow or System Overload. (-10010)

I keep getting this error when I'm playing a song that has 16 tracks and effects on each track, but each track is frozen (!): CoreAudio: Disk is too slow or System Overload. (-10010). I'm running a G4 and have 2G RAM. Is this common? What can I do to prevent this? Thanks for any advice you can give!

In addition to Rohan's suggestions you have more options depending on how you work and what phases of the project you are in.
Something overlooked very often is polyphony enabled for the EXS24-some patches are set to 64 drop the polyphony to either the minimum you will need or less (if less you will notice older notes cutting out-but you can set it to the necessary number upon bounce or export). Some mono patches from sound designers are set to 32 or 64-even if you enable unison this is often worthless.
Up your buffer size-I usually have my PBook at 512-I usually do offline editing, location recording and sound design with the book anyways.
Export the track.
Set virtual memory in EXS prefs to 'on' and with the largest RAM allocation-slow disk, lots of activity.
If you use certain exs patches often but only parts of them trimming the excess off the instrument can improve performance. If you have a piano program with good samples you can initially create a lite version with 2 velocity layers and then when it is time to get things sounding good revert the instrument to the original 5 layer-obviously this makes a huge difference depending on what you are using the piano for, leave it if it is critical.
Save the Channel strip and export as audio file while keeping the sequence in your session. Like Freezing but you can manually trim the file start position and set the bit depth. Freeze files render from the start until the last audible sample and then truncate the tails, meaning even if you can't hear it it is still pulling "silence" from disk as long as there is sound after it. Exporting as 24 or 16 bit will effectively reduce your file size by 25 (24bit) or 50 (16bit) percent. If you know you don't have to edit a performance for weeks to come exporting it will solve alot of problems for CPU.
Someone should back me up on this one but at the moment I want to say EXSamples load into memory regardless of freeze settings-reducing your resources.
Disable the filter (if live or playback-N/A with Freeze)-it is often not critical for some patches. The more synthetic sounds or sounds with fewer/shorter samples rely on them.
Disable Unison.
Most sample libraries were not recorded at 88/96k-there is no benefit in running them in sessions in these Sampling rates as far as the EXS sound quality goes.
That should keep you busy for a while, just some tuning to up your system performance.

Hi i use a macpro i7 wt 7200rpm internal drive i get this message Disk is too slow-(prepare) (-10001) when i am using logic 9

Hi i use a macbook pro 17" 2.66ghz intel core i7 with 8gb ram & a 500gb@7200rpm internal drive i get this message "Disk is too slow. (Prepare) (-10001) when i am using logic 9 wiyh just a 5 vsts loaded 2 of them being esx24's . i used to not get this warning earlier in the same or even heavily loaded projects.
When i press play the beachball appears for a minute or so then the message.
Even when i open up a new project a beachball appears for about 30-40 secs and then the project opens up
i have even tried opening up the projects w/o any vst's loaded (i have disabled them from audio units manager)
Initially i thought it was a hard drive problem so apple had it replaced for me but i am still encountering the same problem.
have even tried disabling the sudden motion sensor from terminal no luck there too
tried reloading osx 10.6.7 no luck there too
what do i do

How full is your 500 GB hard disk?
Do you have 10% to 15% free space available?

Disk Is Too Slow (prepare)

Hi All,
I see this error message when trying to start playback sometimes.
I get the beach ball for about 10 seconds, then the above message.
it may do this several times.
if i leave it a while, a few seconds, maybe re-locate in the track, it will play fine.
yes, a heavily loaded session, but not heavy on Disk I/O.
track plays fine, except when this happens. have seen this on several sessions.
does anyone actually know what this error means? (prepare)?
Thanks,
James.

re: VM for EXS, the settings are disk speed: medium, activity:
try :
DD speed = Slow
HD recording = Extensive
These setting will use more ram !
Xbench says by audio HD on the ATA-66 buss has a score of 50.1.
This is very slow !
look at that :
I have run Xbench on a G5 2x2 here are the marks given by Xbench on different configuration (higher is better)

268 with the Rocket raid card in slot 4 and 6 Raptor 10 000 with Softraid driver optimize for digital audio
I think this is a glitch in how logic is preparing playback vs. speed of the disk.
with so many plugs, full PDC etc, maybe it has too much to queue up to start playback?
From what I have noticed ; playback is prepared by a sub task (tread) in VM (correct me if I am wrong )
You did not answer to my question : what is on the FW bus ? the POCO FW and .....

Error message: "Disk is too slow or System Overload."

When I try to record from the line-in on my MacBook Pro (2.16GHz, 2GB RAM, 100GB 7200rpm HD), I get after some time (that can range from a few seconds to a few minutes) the error message: "CoreAudio: Disk is too slow or System Overeload. (-10010)".
This is weird because I get that error even when recording into an empty project. I have no such error on my old PowerBook G4 (867MHz, 512MB RAM) with the same version of Logic Express (most recent). Both computers are fully up-to-date.
I also get that error on my MacBook Pro very often when I'm working on a project and it's getting pretty annoying, it sorts of halts the process each time...
I also have Mail, iCal and Adium running at the same time as Logic Express, none of which use much CPU so the problem can't realistically be from them...
Any help to resolve this issue or at least shed some light on the potential cause would be greatly appreciated!

Simply having idle applications in the background is probably fine, but I certainly believe that something like Mail checking for new messages in the middle of recording in Logic could cause problems.
I would also check Activity Monitor to see if you have any background processes running that you aren't aware of. My wife's iBook slowed to a crawl once, and I discovered that a printer driver she installed to use a printer at work was using about 80 percent of the CPU.

Disk is too slow or System Overload. (-10009)

Hello all,
I'm running a G4 PowerBook, with 1.67 GHz, and 1.5 GB DDR SDRAM. My Logic set-up is Logic Pro 7 and a Motu 828mkII.
My present Logic project contains 7 tracks, with EXS24 through 6 tracks and Sculpture through the last. The instruments were triggered through a midi keyboard.
While trying to score a short film, I keep running into the following error:
CoreAudio: Disk is too slow or System Overload. (-10009). The error happens while recording and during playback only. There are times when I do not recieve the error message, but playback is terribly jerky and I'm unable to clearly see exactly where I am on the timeline.
I have searched for similar errors on this site and cannot seem to find an answer. I imagine the solution is changing the way I have my I/O setting in the CPU usage. Am I on base?
I'd appreciate any help,
Kris

Hey Cyril and 25G's,
Well I went out and bought a OWC Mercury Elite Pro Firewire 800 with Oxford 912. I transferred the EXS Factory Sample files to the OWC drive. Then I deleted the EXS Factory Sample files on the OS hard disk. Then I created the alias for the Samples and placed the alias back in the Logic file under Application Support on the OS hard disk.
The alias' seem to be working because the Logic project works. The only problem is that it is still terribly jerky.
The CPU is maxing out while the I/O meter is not responding at all. Could this be the clue to my problem?
(Also, Cyril, call me stupid, but I cannot find the Virtual Memory portion in the EXS Preferences.)
Thank you for all your help. (I am a bit slow myself when it comes to Logic and the proper steps to de-bugging a problem. So, very detailed explanations are appreciated)

"Disk is too slow/system overload"??? Help!

Hey
I'm running Logic Express on a G4 with OS X 10.4.10. My processor is 450 MHz, and my memory is 896 MB SDRAM. When playing back around 6-7 tracks, i get a message saying:
"CoreAudio - Disk is too slow or System Overload (-10010)"
or
"CoreAudio - System Overload. The audio engine was not able to process all required data in time."
I'm assuming that this has something to do with my processor being too slow, however, according to the logic express requirements, i have much more than required. Or this could be a problem with RAM maybe, considering i only have 896 opposed to the 1000 needed.
Sorry if this is a noob question, i'm new to macs in general. I'm just looking for answers because this is keeping me from doing what i love. Any answers appreciated!
Thanks!!
EDIT: I'm using a presonus firepod for an interface, if that helps.

I'm not sure where you read the system requirements for LE8, but looking at my box I see that you need a "1.25GHz or faster PowerPC G4 processor (and) 1GB of RAM." Keep in mind that these are minimum requirements.
Unfortunately, the processor is your main problem . . . LE8 requires a processor almost three times as fast as your 450 MHz. Also, as you pointed out, you don't even have the minimum 1GB of RAM. You do have the proper OS, but I don't know if you have the minimum required 6GB of available disc space.
Other than upgrading your processor or buying a new computer, the only other suggestion would be to make sure you record to an external drive but I'm not sure how helpful that would be in your particular case.
I'm sorry I couldn't be more helpful.

No Audio Playback due to Error Message "Disk is too slow. (Prepare) (-10001)"

Out of the blue, no audio playback. Was working just fine earlier today.
I repeatedly get the error message:
Disk is too slow. (Prepare)
(-10001)
NOTE: I have more than enough disc space. That is NOT the issue.
I also just got a second error message:
Part of the Project was not played
This project has too many real instrument tracks to be played in real-time. To optimize performance, see the 'Optimizing GarageBand performance' page in GarageBand Help.
NOTE: Odd as I have only 2 tracks in the GarageBand file.
Any others experience this? Suggestions?

Have a look into the Preferences folder (YourUserFolder/Libraries/Preferences/) and trash all Logic preferences.
You'll have to setup the program again.

Why am I getting this error message, "Disk is too slow. (Prepare) (-10001)"

Hello all! I've been using GarageBand for a while now and I've accumulated quite a few files. Along with all of my movies and iTunes library, my internal hard drive filled up rapidly and I didn't catch it. I received a warning message on my screen one day saying that my hard drive was nearly full and I only had a few MB available. I'm using a 150 GB Solid State Hard Disk on my 2009 MacBook Pro (2.6 GHz Intel Cre 2 Duo, 4 GB of RAM). I remembered reading a while back that it's better to use an external hard drive for pretty much everything when using Garageband, so I bought one. I now have a seagate 500 GB, 5400 rpm external (USB 2.0) and I moved ALL of my movies and music over to it. I freed up around 60 GB of space on my internal hard drive in doing so.
So now that I've given you a little background, let me explain the issue I'm having. Before I noticed that my hard drive was full, I started receiving this error message:
Disk is too slow. (Prepare)
(-10001)
Upon receiving this message, I was unable to do pretty much anything in GarageBand. I couldn't listen to tracks, export to iTunes, or do anything! All I'm using GarageBand for is editing. My band and I do all our recording (and mixing) offsite at a separate studio and i just deliver a 2 track stereo signal (L/R) to my MacBook. From there, I just cut the individual tracks from a block of 30-45 minutes of recording because we just record our entire studio session and mix everything there. I pretty much never have more than two tracks and a few effects going at the same time.
After I realized that my disk was nearly full, I consulted my brother-in-law. He's head of the IT Deartpment at a major hospital here in West L.A. and he told me that I may have created a problem with the cache by filling up my internal hard drive and that I may still have issues with performance even after I free up space. He then told me that I may need to reboot my MacBook a few time to "free up the cache" (or something close to that, sorry guys I'm not that tech-savvy). It seems he may have been right, as I'm still experiencing the same issue. I rebooted around 10 times overall to no avail. I'm still using my internal hard drive to store the files that I'm working on (temporarily) because USB 2.0 is way too slow for my liking, when using GarageBand.
I've read quite a few articles on this offering solutions such as:
1. Do a complete Uninstall and Reinstall of GarageBand
2. Clone my hard drive to my external, format it, and reinstall everything back on it
3. Get a hard drive that supports Firewire 800 (The HDD I bought is USB 2.0, but it has two USB cables to increase speed, but I only have 1 port and I tried a powered USB Hub, but this HDD won't work with it for some reason).
4. Use different editing software.
5. Take it to Apple!
Will any of these things fix my problem? Are some better than others? Before I do anything, I wanted to ask this question on the furum to see if anybody had an easier (or cheaper!) solution. Any suggestions, tips, or advice would be much appreciated, as my band is starting to get on my case about finishing our CD! Thanks...

Error message trying to reproduce the demo songs on the pack. A message appears: The disk is too slow o there is an overloaded. My system is in Spanish so maybe the message is not exactly like this in English but I am sure you will get the idea. Thanks!

When I try to reproduce the demo songs that comes with the Logic Studio pack a message pop out : The disk is too slow or there is an overload.
Any help, please?

spheric, thanks a lot!!!
You are right, as soon I copied the songs to the HD all of them works perfect!
Thanks a lot!!!
