Hard drive constantly clicking

The 2TB hard drive of my 2011 iMac is almost constantly clicking like toc-toc....toc-toc....toc-toc, with a frequency of about 30 times per minute, while "at rest" (no activity from keyboard or anything). Funny thing is, it does it too when I'm running Windows (through Bootcamp). Is this normal?

  • Hard drive constantly spinning up and down when asleep

    Hi all,
    I have a problem with an external USB 2.0 hard drive connected to my Mac mini (late 2012).
    When I put the computer to sleep the drive spins up to speed, stops, then immediately starts to spin up again. This goes on and on.
    I understand that drives will periodically spin up when asleep for spotlight indexing etc. However this seems like strange behaviour, it just repeats spinning up and down in an endless cycle.
    I have had the drive for a while now, as my time machine backup. Interestingly this problem only started after I rearranged my desk when I set up a second monitor. I have a USB 3.0 drive (my scratch disk) that behaves normally.
    I have drives set to not sleep in preferences.
    I have searched around but can only find posts about people not wanting to wait for drives to spin up when they open finder etc.
    What do you think? Could the drive be on its way out? It is a Samsung spinpoint f3 1tb in an Iomega enclosure, for information...
    I appreciate any help,
    Cheers,
    Mike

    Hi BDAqua,
    I should have noticed this earlier but it appears the problem is with the mini waking from sleep and thus causing the drives to wake.
    When I put the mini top sleep (without the external drives powered on) it constantly wakes and sleeps. The displays dont come back on (untiul you click the mouse or hit a key etc.) but you can hear the internal drive spin up and the sleep light comes on, then goes back to blinking until it wakes again.
    I have realised that it must be due to the second monitor that I have connected via the mini display port. It is connected using a mini display port to hdmi cable I bought from play.com. Something to do with the  display and thunderbolt is casuing the sleep function to misbehave, I think.
    Here is the console log that was created after sleeping the mini, allowing it to go through its weird sleep/wake cycle then fully waking it up again.
    Hope that makes sense, it is late and I am tired!
    Thanks for all your help.
    Mike

  • Machine will not boot; hard drive makes clicking noise

    My G4 will not boot up.
    Here are the symptoms:
    It passed the hardware test;
    Will not perform a safe start - so cannot run disk utility;
    Hard drive makes a clicking noise.
    I'd appreciate any advice about how to proceed.
    pdh

    Yes, as mentioned backup now. best not to use your Mac till you do. The drive may fail for good. Here's some tips on replacing your drive (they are pretty inexpensive now);
    This is by SDMacuser,
    Even if you have never installed nor pulled a HD from a Powermac...... trust me....it is not all that difficult.
    I can actually switch internal HD's among 3 separate G4 Towers I own in a matter of minutes (often less than 10 minutes).
    Simply power the system down and ground yourself (a grounding strap is recommended or at the very least touching the metal frame to discharge any potential static electricity prior to actually touching the HD or any internal components on your system).
    Disconnect the power cable to the back of the HD, then the long ide connector on the back of the HD / cable (pull straight back while grasping the black connector with 2 fingers ... do not yank the actual ribbon cable).
    All of my HD's are mounted or bolted to their own metal sleds (either single sled or a dual sled) with 4 screws.
    Unscrew the small screw (philips) holding the sled in place on position one below the ide connector or cable. And gently remove the sled & HD from the Powermac without bumping / damaging other internal components.
    Remove the 4 screws from the sled itself holding the HD in place. Be careful not to allow the drive to fall once all screws have been removed.
    Install the new HD (and make sure to address proper jumpers on the back of the HD itself.)
    Now reverse this process with new HD for proper installation into the G4 Powermac.
    Any questions just post back.
    btw ... there are a few QT demos on apples web sites showing how to do this.
     Cheers! DALE

  • Macbook Pro mid 2010 hard drive beep, click, freeze BACK after Lion?

    I have a mid-2010 Macbook Pro and I had the same problem that was described here:
    https://discussions.apple.com/message/9817201?messageID=9817201#9817201
    https://discussions.apple.com/message/15055210#15055210
    Like many others, mine stopped beeping after the Software Update released by Apple when they admitted there was a problem.  However, since I've upgraded to Lion, the hard drive is back to its old ways of beeping, clicking, and freezing.  Anyone else having this problem again?  Anyone else think this is an odd coincidence?  I called support and, after going through the usual troubleshooting, they escalated to a supervisor who wanted me to go through the same troubleshooting only to tell me that I should take it into an Apple Store where they'll likely send it in for testing.  I haven't done it yet because it's rather inconvenient to have to jump through the same hoops and be without my computer again when the problem seems fairly obvious based on my history with this machine.  I'm actually hoping it's hardware failure at this point so I don't have to wait for them to acknowledge another problem. 

    Hi Luke,
    The click/beep was happening more and more and was starting to drive me nuts.
    I contacted Apple/Seagate but neither were helpful at all.
    I went to my local Apple representative but they said they would need to hold on to my laptop for 1-2weeks while they checked out the issue and then replaced the HDD and the same model, this was something I couldn't do as I need my laptop for work everyday.
    Apple's online support (+ call) just told me to bring it into my local Apple representative so that went nowhere.
    In the end I shelled out my own money to fix Seagate/Apples problem and bought a Seagate Momentus XT 500GB drive which I have had no issue with since I got it, about 6 months.
    It also speeds up my Mac with the inbuilt SSD cache. I recommend it.
    http://www.seagate.com/www/en-us/products/internal-storage/momentus-xt-kit/
    I also just saw that Seagate now offer a 750GB model.
    FYI, I had this click/beep issue in Snow Leopard too.
    For anyone doing a google, here is the exact HDD I have now which works well:
    ST95005620AS:
      Capacity:          500.11 GB (500,107,862,016 bytes)

  • IMac hard drive is clicking and keeps crashing

    Am really getting quite concerned about my imac. It's 3 years old (Apple protection plan just ended a month ago!!) and over the last month or so I've noticed it keeps making a loud clicking noise coming from the hard drive (righthand side if the computer), on one occassion it started to make a loud whirring, like a fan, but was fine once I restarted. In the last couple of days it's crashed/frozen several times (whilst making the clicking noise) and I've had to restart it. Today I lost 2 files I was working on as they became corrupt after the crash. I keep reading that these noises can mean the hard drive is about to fail so I am really scared now. I'm not very good with technical things and I work as a freelance designer so my imac is my life!. I've done a What should I do?
    I keep all my work files backed up on an external hard drive but do I need to do any kind of special back up incase?

    There is no incase your drive is failing.
    Make sure the drive is backed up. A  clone in this case would be a good thing to have, this way when the drive totally goes you can boot off the clone and continue to work until you decide what you are going to do with the system.
    good luck

  • Hard drive constantly being searched

    Ever since I updated to Mavericks my Hard Disk constantly searches. I have tried turning off Spot Light Indexing and Time Machine. I have even reformatted the HD and reinstalled the OS and then re-installed all my files and apps. By the way I could not find a good posting on how to easily do that, took me 2 days and hours on the phone with Mac support. When I look at the Activity Monitor it shows the Kernel is constantly accessing the Hard Drive. Is there anyway to go back to Mountain Lion?

  • Hard drive constantly running with Lightroom 6

    Ever since I upgraded to Lightroom 6 my hard drive hasn't taken a break while Lightroom is open. It constantly runs until I close Lightroom.  Another issue I'm having is not all my NEF files are converting to dng?  Anyone else having these issues?

    Nah...if you choose a less-than-sensible setting in BIOS, an arm holding a hammer will come out of the LCD and smack you...that's a part of ThinkVantage that only a few people know about...
    How many processes do you have running on a freshly booted machine?

  • Why is my hard drive constantly running and how do I stop it?

    My hard drive is running constantly and I can't find out why.  I thought my hard drive might be at capacity so I threw away and backed up a lot of stuff, but it is still running all the time.
    On a PC I know how to find what is actually running behind the scenes and how to stop them, but I don't know how to find those same programs on a mac.  Any help would be appreciated, Thanks

    On a PC I know how to find what is actually running behind the scenes and how to stop them, but I don't know how to find those same programs on a mac.
    Open Applications/Utilities/Activity Monitor.
    With that, all processes can be seen, all CPU, memory and drive use can be monitored and any and all processes can be monitored, sampled, halted, etc.
    My hard drive is running constantly and I can't find out why.
    A new drive will have indexing running continually until the indexing is done.
    mdworker is one of the indexing processes.
    Are your Energy Saver Preferences set to spin down hard drives when possible?

  • Trying to clear a hard drive and clicking doesn't work

    Am trying to clear an 1999 strawberry iMac hard drive for someone before sell or dispose of it. It is running OS 9.
    The computer has not been turned on for 11 months. It will boot and the mouse cursor will move around the screen. If I double click on the hard drive icon, nothing happens. If a dialog pops up that has an accept that is return sensitive, that will work. So it not the mouse or keyboard.
    The menu line nor any dialogs are clickable or openable.
    I get a network time error dialog saying that the Mac clock is set to a year before 1973 and need to manually reset the date and time control panel (which I can't open). The clock on the menu bar says it is a Monday morning time.
    I have booted hold down return and nothing is clickable.
    I zapped pram with no effect.
    Would a bad battery let it boot but not operate?
    Short of tearing open the iMac and sledging the hard drive, any other options? A family might want to have an inexpensive but old computer for a child (once I take off the person's data files). I have to clear or destroy the hard drive if it is junked.

    I replaced the battery and the problem was still there. After a few minutes the computer shut down and nothing since.
    To clear the data on the hard drive, I opened the drive and bent the crap out of the discs. The computer is headed for recycle

  • Hard drive constantly cycling after 10.5.2 update

    I'm not sure if I'm just more aware of it, by my hard drive seems to be cycling constantly since I upgraded to 10.5.2. Everything else seems to be working normally, but I'm concerned about the non-stop activity coming from my drive.
    Any thoughts?

    I seem to be having the same problem. My Time Machine drive is an external FW800 drive, which I have set to sleep whenever possible. Since 10.5.2, the drive will go to sleep, only to be awaken a few minutes later, cycling like this ad infinitum. I checked activity monitor and neither installdb or a print job is running.
    I thought maybe a restart would help, so I restarted the machine and let it sit there with no apps running save Activity Monitor. The drive did the same thing, andI didn't see anything spike when the drive awoke, save for a tiny blip with mds.
    Is this happening to anyone else?

  • Hard drive constantly reading Imac

    I have an imac 24inch (early 2008 model) and have had it repaired once for ram failure and 6 months later there is a sudden juddering sound coming from the hard drive.
    Basically even when not in use the hard drive seems to be reading itself constantly. Something which i am worried about.
    I have verified disk permissions, repaired disk etc and nothing. I have also run the Tech Tool Deluxe software which claims everything is in order.
    I was wondering if this problem is worth contacting apple towards or is it completely not serious.
    Oh and i also have apple care should this problem need fixing.
    Thanks
    Justin.

    Your welcome!
    Go up to the top of the Activity Monitor window and make sure that "All Processes" is selected in the box and then look at the open Process. The one(s) that are showing numbers in the list below the % sing are the one(s) currently working.
    It may or may not be dyeing, but there is nothing you can do for a noisy HD except have it replaced.
    +Example: the original 160GB Seagate Barracuda that came in my Early Core Duo was a little noisy from day one, but it still refuses to die. For size reasons more than noise, I removed it from my iMac and put it into an External hard drive enclosure to use as a bootable clone drive.+
    Please post back and let us know what Apple Care has to say?

  • Hard drive constantly active?

    Hi all,
    Couple of days ago a friend of mine asked me for help with his iPod 3G for the battery runs out of power in a very short time. Closer inspection revealed that the hard drive is constantly active and spinning. Since I have never encountered such a problem I hope someone here might no a solution.
    Thanks everyone.

    Leroy,
    I did restart in Safe Mode and the computer seemed to run fine. Then went to System Preferences/Accounts/Login Items and removed what I thought were the suspect programs, namely Shove Box, Butler, and Smart Reporter. I then restarted my computer normally, and left it on all night. Now the computer is back to running very slowly without the suspect programs running. To give you an example, iTunes took over 45 seconds to load completely.
    The question I have is how do I tell what programs are not loaded when I boot in Safe Mode and what programs are loaded when do not boot in safe mode. That way I can try to figure out which program is causing the problems. I did review the article you linked to, and could not find anything that looked problematic except that the Caches folder in my Library folder is 905.3 M. As I write this my hard drive is whirling away for no apparent reason.
    In reference to The Hatter's comment, that I could have a corrupt Spotlight index or database would that fit in with the facts that we have thus far?

  • Is it bad for a hard drive to click? because when ever i pick up my mac is mac a click noise near the hard drive and people are saying it is sms or something?

    ??

    SMS means "Sudden Motion Sensor." Its purpose is to immediatly park the hard drive head to protect the drive platters from damage, whenever sudden motion is detected (like the laptop falling quickly toward the ground).
    Read this for more info:
    http://support.apple.com/kb/HT1935
    I don't normally hear the click on mine, though I guess some people say it can be audible. Maybe it depends, like the way some hard drives are louder than others.

  • New hard drive - Loud click followed by 3-4 quick clicks descending volume

    2006 Mac Mini Core Duo, just replaced the hard drive because it was clicking - just like as described in the subject line. Now the new one clicks the same way if the Mini is on for for an hour or more, just streaming a movie from Safari. It doesn't exhibit any clicking sounds starting up. When it clicks, it'll be one loud click, a pause, then 3-4 quick softer clicks, probably every 5 minutes. When I sleep the Mini for 1/2 hour and wake it back up, the clicking goes away.
    I did a Disk Utility verify and it said everything's okay. I followed the hard drive replacement instructions to the letter and blew out all the dust, but I still wonder if heat problems have anything to do with it or if the machine is just old. I also play a lot of movies and tv shows from an external drive if that adds anything to the picture.
    The original hard drive was about 70 gigs, the new one is a Hitachi, about 500 gigs.
    I'm pretty sure many will recommend buying a new hard drive, but is there a possibility that it's the computer itself?

    Sometimes one person's click is another person's clack, so it is difficult to diagnose problems based on someone else's description of a sound. Some drives are unquestionably noisier than others but it would be strange that two different drives would have the same sound pattern. From your description and the association with the hard drive it is tempting to assume the sound you are hearing is mechanical in origin but is it possible what you are hearing is electrical in nature? In other words the snap of a static electric discharge? You said you blew out the dust, but are you certain you got all the dust bunnies? Sometimes a computer vaccuum or even a soft natural hair brush will get dust bunnies that canned air will miss. If you use canned air be sure the computer is thoroughly cooled down before using it and spray in short bursts to avoid liquid air at very low temperatures from getting on computer components and risking breaking them.

  • Hard drive constantly running and ruining battery life

    Hello,
    I recently got an x200s from a legit ebay lenovo seller that came with an upgraded 500gb 7200rpm hard drive.
    The problem is that the hard drive is running at All times. I can tell from the sound as well as slight vibration. Even with the lowest power settings, and just letting it idle, it runs. I tried playing with the power manager, and having the hard drive stop activity after 30 seconds of inactivity, it keeps running. I turned off indexing on the c as well as the lenovo back up drive, its still running. The hard drive activity light is only flickering, and the processes seem totally normal. What is up?
    I'd say this also has to be the reason i'm only getting like 2 hours with the 4 cell  and very low power settings, which is unacceptable. 
    Any thoughts?
    Thanks guys
