Clicking noise from a laptop HDD

I'll give you a link for a dead topic in which a user explaines a problem similar to mine: https://bbs.archlinux.org/viewtopic.php?id=39450
I'll also write some similar stuff here.
It's been almost two years or so since I get these now-and-then clicks from the hard disk drive. Some say that the noise is produced when the head is parking. But the noise here comes when the disk performs a read or write too. Also comes when it's idle, sometimes.
Here are some of the "stats" for the drive.
APM_level = 254 (hdparm -B, also tried 255, but it feels the same (maybe the drive doesn't support a full APM off?)

I guess that the "Load_Cycle_Count" is still in "boundaries" of 600000, so it's ok. (although the HDD is 5+ years old).
Should I switch to hdparm -B 255 and test further, even though the clicks apear anyway?
(I'm also considering to buy a new drive soon, definitely an SSD, since this one is probably dying.)
Cheers!

@op - on an older machine, I have bad sectors that need to be repaired:

  • Question Mark  clicking noise from internal seagate HDD

    this morning, my six months old MacBook black (2.16Ghz) screen froze. After force to reboot, my MacBook will not boot anymore while hearing a repeated clicking noise from the hard drive.
    I tried Disk Utilities from Original Install Disk but the internal HDD is not recognized.
    Then run the Apple Hardware Test, 01 Error found with these code; 4SNS/1/40000000:TB0T.
    I don't know what that means.
    Boot up MB from Data Rescue II boot CD, still the internal HDD cannot be found.
    I know that the internal HDD is not completely dead because I still hear a repeated clicking noise from the hard drive. Is there any ways to recover data from the drive?
    Someone suggested me to create "image" out of the hdd by using "dd" command under Terminal.
    Would it be possible?
    I have Apple OEM (Seagate) *ST9160821AS Momentus 5400.3 160gb.*
    Any suggestions? Thanks!

    I've had my share of hard drive failures, and that repeated clicking sound is a telltale sign. Yours is not the infamous Firmware 7.01 drive which were all of the Seagate Momentus 5400.2 series. Sounds like a simple random crash. Unfortunately, these things happen.
    You might be able to recover it yourself. If you can't, any repeated efforts to do it yourself could reduce your chances of recovering data if there's something like a failed head.
    If your data is that valuable, you might want to bring it to a data recovery service. Most will give an estimate and only charge if they can recover data. Their services will typically be very expensive - around the cost of a new MacBook.

  • Equium A100-147 - Clicking noises from the HDD

    For a while I have had clicking noises from the HDD and when the laptop failed I assumed the drive had packed up but when trying a replacement nothing happens. I get a blue light for battery and a (faint) blue light for DC supply but nothing for power or disk. However, when I connected an external drive yesterday it booted fine and when I disconnected it the laptop continued working from the internal drive. But again this morning it is dead and cannot boot. I have read that the BIOS can stop recognising the drive or maybe the settings are not being saved when it is turned off. Could it be the motherboard battery ?

    If I understand you right your notebook is death now, right?
    I really don't know what to do. Remove the battery and HDD and try to start notebook. if the same happen again it is time for new notebook.
    I don't think repair is best option because it can be pretty expensive. Satellite A100 is pretty old notebook and you can sell it on eBay. Someone will need it for replacement parts.
    Maybe my opinion sounds stupid but I don't know if you have time to search for new parts. I cannot say for sure but there must be some serious problem when you cannot even enter BIOS settings or see anything on the screen.

  • Horrible buzzing and clicking noise from the fan - DV6 3046eo

    Hello!
    Two weeks ago the fan on my DV6 3046eo laptop began to make almost continueosly buzzing and clicking noise. My laptop is less than an year old (bought in December 2010) and such noise has never occurred before. I have done some "research" to find the reason, but without luck. I have read on Internet that the fan may be broken or loose. I am just using the web and listening the music. I have to admit I played some demanding games on the computer, like BBC2 and Dirt3. But the problem occured later. I can't imagine what will happen if I play games on my laptop now...
    The fan seems to cool down the laptop, but it is like something is hitting it every third second or soand preventing it from running silently. The noise is strange and irritating because the frequency changes rapidly. Sometimes when I move the laptop or hit it a bit gently, the loud noise suddenly disappears and the normal continueosly noise takes over (I am ok with the latter one, though). After some while it appears again. The noise come and go. Reboot doesn't help much. I have also used an airspray can, but to no avail. I am thinking about getting the fan replaced by HP before the 1 year warranty runs out. I am not too comfortable to do so myself. What's the reason for this noise and what should I do?
    Thanks in advance!
    Sandip

    Still no comments?
    I am getting sick of this noise. I can't bring my laptop to school because it makes too much noise. Please help me.

  • Clicking noise from back-ups

    Since replacing my G5 with a new mac mini I hear frequent clicking noises from the APC Back-UPS that I have it plugged into. The only obvious difference is that the mini has an ungrounded two-prong plug while the G5 had a grounded three-prong plug. The clicking noise consists of two clicks in succession, the second one slightly lower in pitch. This occurs at random intervals but also in response to anything that I'm doing on the computer such as opening or closing an application, resizing a window, visiting or exiting a website, etc. Occassionally it will happen when the computer is asleep in which case I will hear the fan running briefly in the mini although the monitor doesn't wake up. When this happens I will often see the internet activity monitor light flashing on my dsl modem. I don't know if these noises are a sign that something isn't working properly or just an annoyance. In either case I would welcome suggestions on how to stop it as well as any ideas as to what might be causing it. The APC unit provides battery back-up power in the case of a power outage and surge protection. I submitted my question to APC support but got no response. I also talked to someone at AppleCare and he had no idea what was causing this and wasn't even sure if he knew what I was asking about. However lots of people use back-ups units so someone out there must have experienced this phenomena besides me.

    I checked that box but wasn't around the sleeping computer long enough to tell if it made a difference. I plugged in a lamp with a dimmer and turned it up and down with no effect. Then I had an idea. I'm going to wait a couple of days before marking this as definitely solved, but here's what happened:
    The UPS has three outlets marked "controlled by master." Anything plugged into these gets it's power turned off when the computer is sleeping. I had long ago moved the peripherals to the other outlets because I didn't like having my computer and monitor wake up whenever I turned on the printer just to use the copy function. Near the power button on the UPS is another smaller button with a graphic symbol. If you hold this down for a few seconds it turns off the "master enable" function. After I did this the clicking stopped.
    This still leaves some unanswered (though no longer important) questions: Why was this an issue with the mini but not with the G5? Why was I getting clicking noises in response to doing things on the computer even with the usb connection to the UPS disconnected? Why was I also getting them even when the computer was asleep? One possible factor is the usb hub. The old one was on a pci card, while the new one is external with a power cord connected to the UPS. Another factor may be the ungrounded power plug on the mini vs. the grounded one on the G5. At any rate it looks like the problem is solved, at least for now.

  • Clicking Noise from hard drive_U410

    Hi,

    How can I fix this?

    HI,

    Thanks!!
    The noise you are hearing might just be the normal sound of the hard drive.  Most hard drives aren't 100% quiet.    The link below is for a Seagate article on hard drive noises for your reference......
    http://knowledge.seagate.com/articles/en_US/FAQ/174571en?language=en_US
    Are you experiencing any errors or problems with the hard drive ?  Seagate also offers a free SeaTools utility that can be used to check the health of your hard drive.  You can download that free tool at the link below.....
    http://www.seagate.com/support/downloads/seatools/
    As for warranty, the hard drive would be covered under your computer's warranty and that would have expired after 1 year. 
    As for fixing the noise, the only way to fix the noise would be to replace the hard drive with a new one.  Then again the noise you are hearing maybe just the normal sounds of the drive. 
    As with any hard drive it is always a good idea to have a back up of your important files on another media. Hard drives have been known to fail without notice.

  • Clicking noise from the HDD of the new Mac Mini

    I just recently purchased a new Mac mini to retire the Macbook pro from my leaving room (it was heating up too much when running Plex). The problem I find is that the new Mini's HDD (toshiba 5400) has a loud clicking noise which on the MBP I can't barely notice. Is anybody else experiencing this?
    I would like to understand if this is just a faulty HDD so I can exchange it or if the sound is normal and then I would just return it.
    Thanks in advance

    No clicking on my 2010 aluminum model or any of the previous ones that I have had.

  • Clicking noise from new Toshiba Satellite laptop?

    I have a Toshiba Satellite C55-A5195 (Windows 7 Home Premium). It was bought brand new around 3 weeks ago. I've noticed that, besides the fan noise, the bottom of the laptop makes a clicking or buzzing noise. The laptop has blue screened twice, something about memory management. I don't really mind the noise, I just want to make sure there's nothing wrong with the laptop's hardware.
    Any help would be much appreciated, thank you!

    With any physical sounds like that, it can be really hard to know if it's something serious or not. Hard drives, optical drives, and fans all have moving parts that can cause noise.
    In regards to the blue screens, have you installed many programs? Do you know what you were doing when they occurred?

  • Clicking noise from Ac adaptor while charging using 600W inverter

    I am trying to charge my laptop from a 12 volt battery through a 600w inverter.
    However the latop won't charge and the charger just makes a clicking noise.
    Does any one know why this is?
    And can anyone help me?

    I have no idea why the AC adaptor makes such clicking noise but this does not sound good.
    You should use an compatible car ac adaptor for the notebook since wrong car adapter could damage the notebook.
    Would recommend contacting an Toshiba service point in your country to get a right part.
    You could also check some independent online resellers to get such part.

  • Clicking noise from hard disk

    Hello forum,
    one more hard disk noise problem. My new MPB arrived two days ago and I immediately noticed a clicking noise that is presumably emitted by the hard disk. I've got the basic 250GB model, so it's unrelated to the 500GB noise. The sound occurs quite regularly every 20sec or so, but only when the disk is inactive. The system doesn't freeze. The noise appears regardless whether the disk power saving feature is enabled or not. Here is an amplified version of the sound without the normal background noise (fan, hard disk):
    http://www.filefactory.com/file/ah25f1h/n/ClickingNoise_wav
    I've learned that clicking noises are a certain sign of hard disk failure. So should I return it immediately and ask for a replacement?
    Regards

    It sounds like you've got two clicking noises happening back to back, correct? I have the new 250GB drive as well (5400 RPM) and I'm hearing a periodic click similar to the second one in your clip.
    I can hear only the second click, too. Only if I mute the background noise and amplify my recording, I hear the first one. Could you perhaps take a record of the sound that your MBP makes so that we can compare the sounds?
    Haven't noticed any other problems with the drive, though. Is yours a Fujitsu? Mine is, and according to their web site, "if the drive is idle it will automatically move the heads periodically to prevent lubricant migration." I'm wondering if that's what the noise is.
    Interesting. Mine is a Fujitsu, too, and perhaps the two noises come from the disk head starting and parking.
    Actually, it sounds a lot like the 500GB noise, except without the beep. I've seen very few, if any, issues with the 250GB drive, but I'm holding out hope that a fix may come along at some point.
    I agree. Currently the sound doesn't seem to be harmful, but one never knows.

    My 12" Powerbook makes a horrible "clicking" noise when a insert a CD or DVD. After a few seconds the CD or DVD is ejected. This is pretty sudden thing as it was fine one day and now this. Can anyone tell me what may be causing this, or how to fix it?
    Thanks!

    gjortega ,
    Here's the troublshooting guide from the service manual:
    "Startup
    The computer will not power on
    1. Remove any connected peripherals.
    2. Try known-good power outlet.
    3. Try known-good power adapter and power cord.
    4. Remove battery.
    5. Reset the power manager by pressing the key combination Control-Option-Shiftpower.
    Warning: Make sure you do not hold down the "fn" key when resetting the
    power manager.
    Warning: Resetting the power manager will permanently remove a RAM disk, if
    present, and all of its contents. You will also need to reset the date and time
    (using the Date & Time control panel).
    6. Disconnect internal keyboard completely. Inspect connectors. Restart with keyboard
    disconnected.
    7. Remove any additional RAM and AirPort Extreme Card.
    8. Try known-good DC board.
    9. Verify power button is connected properly to logic board, if power button is not
    functioning correctly or damaged, replace the top case.
    10. Replace logic board."
    Now that #10 would be about U28 or the GPU. U28 is that site I sent you. The GPU sits under the option-Apple key and you can put pressure on it from underneath that area. There is a large heat spreader that sits on top so you have to come from underneath.

  • Clicking noise from the screen moving

    My Phone is making a clicking noise on the right hand side of the screen, the movement of the screen cannot be seen but it can easily be felt. ive seen this as a problem before from other questions and how most cases have been sorted, however my phone has scratch marks on it, not from being dropped, just from a set of keys in my pocket! :/ will my phone still be covered by warranty to be replaced?

    No one here can speak for Apple about what they will do. They'll examine it and make a decision nor do we have any idea what they will think.

  • Clicking noise from speakers (not HD)

    Someone suggested that it could be a busted port. However, they did not tell me how likely it was that that was the issue, how I could find out, what that exactly meant, or how I could fix it.
    Basically, I had my HD replaced a while ago. The computer works fine, in fact, better than before! But this constant, loud clicking noise comes from both the external and internal speakers. Right now I am using these portable speakers which I attached to the headphone jack. But I'd really like to use my Mac speakers.
    When there is nothing plugged into the headphone jack. Only the clicking is audible, there is no other sound.
    I know there are more knowledgeable people here who can help. All suggestions and advice will be appreciated.
    P.S. Restarting to the desktop doesn't help. Also, when I restart, I get a message that looks something like this:
    Incompatible device plugged into Mini-Jack. Please remove or make sure speakers are fully inserted.

    Well, I bought new speakers. Thanks for nothing!

  • Clicking noise from left side of body?

    There's an incessant clicking noise coming from the left side of my macbook, about once a second, not from the speaker. I can't tell if it's the top or bottom, but bottom is my guess. What is causing this/should I be worried about it?

  • Clicking noise from back left of MBP -- speaker maybe?

    Hi all,
    I have a clicking noise coming from the back left of my MBP and I'm wondering if anyone else has this problem, has any suggestions, or knows if it is potentially bad.
    I saw the long thread about a 'pop' noise here:
    http://discussions.apple.com/thread.jspa?threadID=1234166&tstart=0
    ... but I'm not 100% sure mine is related.
    I looked at some MBP take apart guides and see that the hard drive is in the front left, but my click seems to be coming from the back left (if I put my ear on the front left I can hear the hard drive spinning and all, but the click doesn't seem to come from it). I tried the hdapm suggestion in that thread just for kicks, but nothing happened, so overall I don't think it's the hard drive.
    The only moving part in the back left as far as I can tell is the left fan, but I checked the fan speed with smcFanControl, and they were both at 2k (normal speeds). Plus, it doesn't sound like something I would expect a fan to make, but I could be wrong. The click happens in bursts usually, clicking about once every 5 seconds (it seems pretty consistent) for a while, but then has long periods without clicking. It doesn't seem to click more or less depending on computer usage. I would think that if it were a fan noise, it would click a lot more often (every 1/2000 seconds! ;>), and I don't see why it would come in and out in?
    I'm wondering if it might be a periodic pop from the speaker. It happens when the volume is down & muted, though, so that seems somewhat odd. If it is the speaker, I don't think it has anything to do with interference, as it will make the noise when the computer is on battery power, with nothing plugged in, far from any electronics.
    Overall, I'm pretty confused, so any advice would be great. At the moment, taking it into an Apple Store won't really work for me :/ I used to have a PowerBook & a G5, but I sold both of them when I bought my MBP, and this is my only computer. I have a NAS that I've backed up all my data to -- so I'm not really concerned about losing stuff if something dies -- but I need my MBP for work, so I can't live without it for a week or so if they need to hold onto it. Does anyone have any ideas about what might be happening?
    Thanks!

    Welcome to Apple Discussions!
    I didn't read all of that long thread, but I have heard of the type of noise you describe being associated with the hard drive. Whether it's benign or ominous or something else entirely is hard to say. But there are a couple of little utilities that can help you evaluate your hard drive:
    S.M.A.R.T. Reporter:
    http://www.corecode.at/smartreporter/
    S.M.A.R.T. Utility:
    http://www.versiontracker.com/dyn/moreinfo/macosx/32454
    The former will monitor the S.M.A.R.T. status of your hard drive and install a beautiful icon in your menu bar. The icon will be green if the S.M.A.R.T. status is verified and red if it is failing. It is designed to give you a heads up if it detects hard drive problems.
    S.M.A.R.T. Utility is not supported on all hard drives, but if it is, it will allow you to see various factors which determine the S.M.A.R.T. status and if there are problems with any of them. This can also give you early warning of hard drive failure.
    Also, there have been some problems with one model of Seagate drive, so check and see if you have a Seagate.
    My Fujitsu drive is absolutely silent, and that is what you should expect. My external La Cie makes clicking noises every so often, and always has, so I think that is normal for it.
    The main thing to worry about is the hard drive.
    Do you have the widget iStatPro? It might be better for monitoring the fan speed without using smc fan control. But if the left fan is at 2000 RPM, then I would expect a very rapid click, which does not sound like it's the case here.
    One last thing--does the click vary with the volume? Does it get louder if the volume is turned up high and quieter if the volume is turned down low? If the click has to do with the speaker, then I might expect the click to be louder or quieter depending on how the speaker volume is set.
    It may be worth taking it to the Apple Store just to let someone listen to it and give an opinion. If you are under warranty, at least get a case number to document the problem. I understand that you can't be without your Mac for a week or so, but if a problem is diagnosed that does need to be fixed, then you can work on getting the work scheduled for a time that is convenient to you. It may even be possible to arrange for a loaner with all your stuff cloned onto it. Knowledge is power, and will give you better options than, say, having a sudden hard drive crash.
    Good luck!
