27" iMac hard drive noise

same here !!!!!!

imracin68j, That's it. This is exactly what I'm getting with my NEW iMac 21.5".
I will be dropping it into the store for a replacement tomorrow.
I surely think that this is a fan noise.

My i5 27" has a WD WD1001FALS 1TB drive and it is silent. I asked the store to let me check out the unit in the back while they upgraded the RAM to 8GB and they let me. It's nice and quiet back there so I was able to verify that everything was quiet -- disk drive, display at low brightness -- and that the screen didn't flash upon wake from sleep, etc. I ran the TechTool from the AppleCare disc and the DVD drive did make a lot of clunking noises on that disk, but the tech let me try some other discs and they all worked fine. He said the TT discs always seem to make this racket, probably due to the formatting for diagnostic purposes.

Oh, and my machine is build week 51.

I have a week 51, 27'' 3.06 iMac with the Seagate ST31000528ASQ drive. I haven't noticed any noise unless I am in a COMPLETELY silent environment, and even then it's just normal humming from the fans and not the HD. Much quieter then my old 2.4GHZ 24'' iMac, which I could here the HD rumbling whenever I copy large files or did other HD intensive tasks. I haven't had any issue with the screen or graphics either, no yellowing, no fuzziness, no flickering.

The only odd thing was SD cards were acting strange at first, it would just randomly unmount, but then after using it a few times I haven't had anymore issues so maybe it just had to break ing or something????

Wait! Give Apple time to sort out its problems. Don't be part of their beta tester's group, just wait. How long? I'd give them six months at least. Good luck....

What I hear is some small knocking coming from the right bottom part of my screen, it is hard to describe it and I don't know whether it is the hd. Can someone tell me where it is located?

And as a totally new Mac-user I can't compare this with anything. Are you guys telling me that the iMac should be totally silent while working, except from some small fan whispering that is?

Thanks

Does someone know where there is a sound recording or youtube vid that describes the bad hd noise. Because I can tell for sure (always used PC) whether it is normal.

These are the facts: The computer is making some weird grumble every now and then, see it as some silent knocking on a table or your stomach grumbling when you have the flue.

I called Apple support and they told me that I should get it back. They aren't ok with my second problem too which is, 7 dead pixels in the iSight.

Should I send it back when you read these issues? or not?

The hard drive is located in the center of the iMac. Refer to this image: !http://s1.guide-images.ifixit.com/igi/TLfSqZEZWnTwKylR.large!

I'm not sure how much you know about computers, but If you can't tell what is the hard drive in that picture, it's the only part that has a green board/chip there.

Is the sound more of a random knocking/tapping sound? That comes and goes even when the computer is idle?
Or is does it sound more like beetles being crushed, and only makes that noise when the computer is not idle?


Hope that helps you 😉

Mine grumbled, stopped for a couple weeks, and just a couple days ago... started up again. I have no idea why. I wonder if it has to do with physical position somehow.

Thanks for the picture, now I can say that I have seen the inside of a Mac too.

Well, it always occurs, even when the computer is in idle. What I also here is a very hard click right before he goes to sleep mode, metal one. But I guess that is normal? No idea.

Which we could have someone who could manage to record his/her drive noise so I can compare it.

I have a week 50 i7 with a 1TB Seagate (ST31000528ASQ) and it is very, very quiet.

@gr8fl4295

Can you put that recording online? Would like to compare it with the noise I hear.
Thanks!

@talar

I have the same disc. Do you hear any grumbling? Even while you are not copy pasting stuff?

Mine makes a very small click right before it goes to sleep as well, so I'd say that's normal. :-/

As far as hard drive noises, It's probably not actually coming from the hard drive if it is making it even when idle. That is possibly a fan rubbing against something it shouldn't, like some others have suggested. IF you believe it to be that, I'd have it checked out at the apple store right away.

I'd like to hear a recording of this if possible as I'm a mac newbie. Coming from a very loud PC I'm not sure what I should be hearing

Mine was silent at first, but is make a little noise now after a month or so.
