Hey all,


Received my brand spanking new MacBook Pro mid 2012 model just a few days ago only to be disappointed by a clicking noise coming fairly regularly from the hard disk. I've plenty of experience with "the click of death" as some call it, and so I called Apple about what to do.


Two options: send it back to them, or go to a Genius Bar and have them look at it. I opted for the later and took it in, explained about the click and they said they'd replace the drive. Great. However... I go to pick it up today, get it back home and after about 5 minutes of using it, and there it is: the click again.


Could I just be really unlucky here and have received a second faulty hard disk? Or could this be something else like a problem with the circuit that supplies power to the hard disk (not enough juice / too much)? Has anybody else received the new mid 2012 MBP and had a similar problem? Could this be down to a faulty batch of 750gb HDDs shipped to Apple?


I know, that's a lot of questions, but if anybody has any ideas or any info, that'd be great!





MacBook Pro (15-inch, Mid 2012), Mac OS X (10.7.4)

    Are you moving it around when this happens? All MBPs have a motion sensor in them that makes the HDD dock the heads when the notebook moves. More then likely that is what you are hearing. Stop moving it around and if and when you do need to move it from place to place close the lid which will put it into sleep mode. ,And if you are usinig it opn your lap/knees stop moving it in a quick motion. Put it on something more stable.

    Then I'd say it isn't the hard drive or Apple really didn't replace it.


    When you got it back were all your programs and files still on it? If they were Apple did not replace the hard drive.


    Simple way around this. Apple has a 14 day No Questions Asked return policy. Us it and return that system and buy another. As it is now that is not a new system, IMHO. Any system a few days old that has something replaced is no longer new. It is used and refurbished. You did not buy or want a Used or Refurbished system. Go return it and get another NEW system.

    No arguement needed. Just take it in with all the packaging and say "I want to return this". they will say OK or at the most ask why. If they ask why say "because I would like to return this". End of story.

    I have exactly the same problem wih my MBP 13" mid 2012 and 500Go HDD bought on 15th June.

    The problem was not present at the beginning.

    Maybe it is due to one of the recent update.

    Waiting for ML to see if problem disappears.

    One more point : my HDD is not a Toshiba but Hitachi :  HTS547550A9E384.

    So I am not sure that this noise is related to the disk itself.

    I have used the laptop with SMS desactivated (sudo pmset -a sms 0) and the click is still there...

    Even though chances are small, but it is not impossible to get a second faulty drive. Or a third for that matter, just really really unlucky.


    It doesn't however look like an issue with all mid-2012 MBPs since I haven't personally seen too many complaints on this issue. Though some less technically aware users might ocnsider it "normal sound".


    Upgrading Hard Drive and RAM (if they are user-replacable) are authorized operations that will not void the warranty unless you break something during the upgrade work.


    On a related note, when I replaced the drive on my MBP, it suddenly started doing the clicking, right after boot up. It seemed like it only clicked if the drive was not active for a few seconds. This of course should be a longer period of time, e.g. 10 minutes, to click and put the drive in sleep mode. It starts spinning again if required. Extra clicking however can and will kill the drive eventually since it's designed and built for a certain number of those clicks.


    The source of the problem was that Apple modfies the firmware of the HDs they include to be compatible with their custom instructions. The drive that I purchased, along with many others are incompatible and that causes the excessive clicking.


    The solution was a tool called "hdapm" which some guy wrote (you can Google it) and fixed the problem for me. No more extra clicking at the cost of more battery usage of course since the drive doesn't stop spinnng with hdapm script run at boot time. The tool hasn't been updated since so now on ML, I have to run it manually on reboot using sudo.


    Point is, this might be one of those cases were a batch of not faulty, but just incompatible (unmodified) drives went into production.


    Either way return and replace is my recommendation too.

    Hi. I'm the developer of hdapm. Lots of third party HDDs suffer from this clicking issue. It doesn't mean your HDD is faulty, but it can be rather annoying. Usually it is third party HDDs that do this, however, so it's surprising if an Apple OEM HDD is doing it.


    I recently released a new version of hdapm which works better on systems that have multiple HDDs, and also includes an uninstaller in the package. It's been tested with Mountain Lion and you should not need to run it manually on every boot with this new version.

    All Apple OEM hard drives are 3rd party. Apple does not make HDD, they buy them from a manufacturer.

    I mean to say: Apple OEM HDDs traditionally have modified settings/firmware and in my experience do not suffer from the 'clicking' issue[*]. It usually occurs in standard, aftermarket HDDs.


    [*] Caused by repeatitive load/unload cycle as the drive enters and exits its low-power state.

    Sorry to disagree with you again but Apple does not load any special firmware on the spinning HDDs they use in any of their computers. They are just standard drives made by any manufacturer, the same as you can buy for multiple vendors. In fact the original drive that came in my MBP is now inside a Windows XP desktop system as the third drive in that system. Working just fine in a home built Win computer running XP. Just need to be formatted NTFS and the partition table changed from GUID to MBR.
