Disk eject sound every 30 seconds

For the past 3 weeks, my iMac is making the 'disk eject' sound every 30 seconds. It's maddening. It persists whenever the machine is not asleep and in both user modes. Any thoughts?

If it's a click click, it may well be the sound of a dying hard drive. Back up all your data to a firewire external as soon as you can, I use SuperDuper! to make a bootable clone.

Chime sound every ten seconds or so in quick time for pc

Getting a "ding-ding" sound every 10 seconds or so when quicktime pro is open. any one know the answer to this one?? Thanks. Jay

fixed. download loaded latest version. Actually had to do it twice. The first time fixed the chime problem but gave me a green screen on playback. So, I downloaded again and used the "repair" button on install, and everything seems to be working ok.

My Macbook Beeps; a high pitched sounds every ten seconds, what is wrong?
Help, please!

buckmacie,
has the video been completely downloaded onto your MacBook Pro when you start to play it? Or are you playing it while it downloads, AKA streaming it?

Apple TV2 unit makes an ultra-high pitch sound every 40 seconds

This just started happening about two hours ago: every 40 seconds our Apple TV2 makes this dog whistle-like sound that pierces through the whole house. Has this happened to anyone else? I have tried recording the sound but the mic on my iPhone can't pick up the sound. (btw, my wife hears it too, in case you thought I was just being crazy haha)

Looks like it was the iPad Mini that was next to my Apple TV2

Macbook Pro frozen with a strange sound every 5 seconds. What happened?

I was just surfing the net and suddenly my macbook pro 13 got frozen with a loud "beep" every few seconds (the same sound as that of upgrade booting). What happened? I've shut down and then it restarted as usual.
Sorry for my english.

Sounds like bad RAM. Run a hardware check and/or take the machine to the Apple Store or AASP.

Help ! Screen Capture sound every 30 seconds

Hi all I need help! Last week in the middle of my work day nothing special, the system started playing the camera shutter / screen capture. I started timing between the shutter, every 30 seconds, very annoying - the camera shutter sound - same as the shift-4 screen capture sound and same as the sound that occurs when you press the back button in terminal. I have a 15 inch mac book pro. 2009 model.
I wondered whether someone had installed a hidden shell script or apple script program and is capturing my screen and maybe sending it over the net.
I have checked activity monitor and did not notice any programs running like "screencapture" or anything else like that. I have also turned hidden files visable on, but i can't find any screen capture directory or files: .jpg, .pdf, .png files I should be seeing lots of them for every 30 seconds per capture. Back to terminal here is my dump from ps ax command:

Please any suggestions??? as you can imagine im pulling my hair out. Please any ideas before i have to reinstall everything again i just finished a re-install. My last system had the Isight camera turning and flashing randomly now this...am i a victim of mac hacking???
Help!!! Pls.

Make sure the sound is coming from your speakers and not from your hard drive, by muting the speakers. If the sound continues, it may be your hard drive's heads parking (which shouldn't happen every 30 seconds either, but that's a very different problem). If it doesn't continue and is therefore exactly what you think it is, I'm as puzzled as you are.

Why is disk space taken every 20 seconds?

Recently, I used boot camp to install Windows XP. I used the partition of 32GB for XP. Now, when I look at the macintosh HD info, it shows that the capacity is 153.88 GB and available are 126 GB. The only thing that I stored after partitioning the HD was 6.96 GB of music. Where did I wasted all of that space? My HD is 185 GB.
Also, everytime I look at the used space, the bytes keep on changing. Does that means that every 20 seconds, the space is being taken away?

Not quite sure I understand your arithmetic. You started with a drive with a capacity of 185 GBs from which you created a Boot Camp partition of 32 GBs leaving 153 GBs. You then have your installed OS X and application software, and, I assume the pre-bundled software of about 16 GBs and 7 GBs of music which is 23 GBs leaving you with about 130 GBs of free space more or less.
OS X will continuously use disk space for cache files, temporary files, log files, VM files, safe sleep file, etc. So, at least based on what you've posted I don't see a problem.

Weird clicking sound every few seconds.

When i open the powerbook from being asleep, it starts up and everything is fine... every few seconds i hear a weird click sound, i'm guessing its the HD, and somthing is wrong with the moving parts. I have not dropped or damaged the powerbook in anyway. I first heard the noise when opening the top after being away few for an hour.
Has anyone else had a problem like this?

With hard drives it's not a matter of if it will fail, it's when. Since they are made of moving parts generally when you begin to hear clicking noises, it's a sign to backup your stuff and then worry about running some diagnostics. If you have applecare you should run techtool and it should tell you with a small margin or error if it's good. Now just because it says that the drive is still good can also not mean that it isn't in the process of going bad. So, keep a good backup of all your stuff on an external drive. I use superduper to do a full backup of my system once a week on a external firewire drive that's bootable if i need it. It will do a "smart update" of your data when you backup after the first time saving you a lot of time.
If you don't have applecare, try and find a friend that does or take your computer to your local apple authorized service center. They will have access to the gsx (global service exchange) website which has specific diagnostic bootable cd's for each model of computer. They should be able to tell you if it's bad or not. If you find a friend that has applecare, just use his techtool cd. Just Boot from the cd and run the diagnostics, don't install the app on your mac as that would be illegal.
Hope this helps

Faint clicking sound every six seconds

I've just noticed that my MacBook Pro emits a faint clicking sound approximately every six seconds. It's a double click, and it sounds like a fairly low freq. It is very regular. I have no idea how long it's been going on, since I live in NYC and am constantly surrounded by loads of ambient noise. I just noticed it while staying with a friend who lives in a quiet neighborhood. (This is how faint the sound is.)
Details on my system: MacBook Pro (13-inch, Late 2011). I upgraded my hard drive from the factory installed one to a Crucial SSD about 10 months ago. At the same time, I upgraded to 16GB of aftermarket RAM, too. Two *GB, 1333 MHz, DDR3 chips. I can't remember the brand, but I bought them from Crucial, too.)
Does anyone know if I should even be concerned?
Thanks.

>, nothing to be too worried about in the short term, right?<
Right!
>I don't need to start taking backups<
Making backups is always a great idea. You never know when your computer will go down.
Thanks for the check mark.

My iPhone 4S Wont Come on, but makes the charging sound every few seconds

I have an iPhone 4S and the device wont power on, but when i plug it in, it repeatedly makes the sound of when you plug in your device to a power source. What is this and How do i fix this?

Try to backup and restore you device in itunes...restoring the device is like removing the iOS software off the device and re-add in a newer software, after you have restore you device, MAKE SURE YOU SET UP YOUR DEVICE LIKE A NEW DEVICE, DONT NOT RESTORE FROM BACKUP!!... give the device a chance to use the newer software and see if the issue still persisting, if the issue still on going then its would be a hardware issue.
Call Apple Care and see if your device is still under warranty to get it replace

My printer makes a loud dinging sound every 5 seconds.

I have no error messages and it prints perfectly. I have restarted the printer and computer. I have unplugged the printer but can't get it to stop dinging.

hi there smallworld100,
could you provide the community with a little more info to help narrow troubleshooting? Mainly your printer model but things like your operating system as well will help out a lot.

Process "mdworker" Writes to Disk Every 10 Seconds

I noticed disk activity occurring every 10 seconds while my computer was idle. In Activity Monitor I could see this writing going on and at the same time the process "mdworker" would tick up just a little bit of processor activity. A Restart didn't help. The following is what I did to make it stop. I've seen many posts on here with a similar problem so maybe this info will be helpful to someone.
I brought up a Terminal window and entered the following command:
sudo fs_usage -w -f filesys
That will show youa continuous list of all processes that are reading/writing to disk (use Control-c to make it stop). I found mdworker doing a fair amount of disk activity every 10 seconds. But the important thing is that it was the identical activity every 10 seconds, and the common thing in almost every entry was "Default Folder X". So I concluded that it was having trouble indexing something about Default Folder's data. (mdworker is used to index your data via Spotlight.) After uninstalling and reinstalling Default Folder, the constant writing stopped and has yet to happen again.
If you're having a problem similar to this you may find this method of identifying the culprit and fixing it useful.

Try this, courtesy of Baltwo. It will delete the Spotlight V-100 index and then force Spotlight to re-index.
Be absolutely certain to only copy/paste these commands exactly. DO NOT try to type these in. One typo or wrong space in the first one could wipe your drive competely. Hit return after each.
Delete the entire Spotlight directory and reindex, running these commands in the Terminal app:
*sudo rm -R /.Spotlight-V100*
*sudo mdutil -i on /*
*sudo mduitl -E /*

Hard disk always working - sync_supers writting to disk every 5 second

As the topic says. My computer is on my desk while I work and I can't stand the noise of hard disk doing something every 5 seconds. I think I noticed this since 2.6.36 kernel.
When computer is completely idle it still writes to disk.
Tried Ubuntu 10.10 and got the same result. I have WD Caviar Blue 500gb. On ext4 filesystem there is jbd2/sda* doing write every 5 seconds or so and on reiserfs there is sync_supers doing the same. I guess those that is journaling acitivy, but its anoying to hear hard drive working when computer is completely idle.
Any tips?

linux wrote:Does anyone know the destination where sync_supers is writing to?
The Linux kernel mailing list has some information that may help on identifying what sync_supers is doing, http://lkml.org/lkml/2012/4/11/147.
While you wait for kernel patches, there are some mount options that other people have suggested may help:
Use noatime or at least relatime for ext* filesystems
Use the option commit=60 or commit=300 to lengthen the time between syncs of data and metadata from 5 seconds to 1 or 5 minutes. However, if the computer crashes between commits there may be some data loss.

Does the CD eject sound sometimes occur repeatedly?

Hello folks,
Recently, when I ejected a DVD from my iMac, the eject 'sound' occurred again twice, AFTER the disk had popped out and I took it out from the slot. It's like the system tries to eject two more DVD's after the first one!
Anyone familiar with this one?
Any help/advice would be greatly appreciated!
Thanks.
Steve.

Hi, we have a very similar problem. Our iMac G5 wouldn't eject a disc recently; we could hear the sound of the drive trying to eject it over and over but the disc would never come out. By tilting the computer slightly, the disc protruded enough to grab it, so now the drive is empty. However, it is still trying to eject, about every 30 seconds or so.
Any ideas why this is happening? We have tried resetting PRAM and resetting using the start up/power cord removal. The drive continues to try to eject a disc that isn't there....
