Got a 27" last week. No noise from Hard Drive but some pixels went out. They replaced it with a new slightly better model, but the thing has the same annoying Hard Drive sound you decribed. I understand the Western Digital HDD are quiet, is that true? And has anyone had success asking the apple store to replace the drive with a quiet one, such as the Western digital?

a new slightly better model? Do you mean you had a late 2009 and got a 2010 model? I just send my late 2009 iMac back because of HDD noise. Do I get a new 2010 iMac in return?

Cheers,

Bas
 
Apple wont replace the HD in store. They will give you a entirely separate replacement computer.
 
I have an i7 with the 2TB Hitachi drive and I'm not hearing any noise from it, so that seems to be one possible option.

Unfortunately that doesn't mean I don't have a noise problem. There is an annoying drone with a period of about a second which sounds like a fan that is spinning slightly off true. It's fairly quiet, but if you're sat in front of the computer in an otherwise quiet study, it gets pretty distracting. I'd expected that if I changed the speed of the 3 fans (HD, CPU and OD) in turn I could identify which one it was and maybe solve it by setting a different default speed. That didn't seem to make any difference though, so I'm now scratching my head as to what else could be causing it.
 
What a Nuisance

First, the Core 2 Duo - the one I just purchased - is a late 2009 build with a seagate 1TB model ST31000528ASQ. It is very quiet, but not silent - way better than the 1TB in the i3s.

If you want to upgrade to a 2TB they are made by Hitachi but there are mixed reports on the noise, quality, and reliability, so no gauranty you will get one that is not noisy.

O.K. let me tell everyone some things that Apple probably won't like. The guys at the genius bar and many apple care techs don't realy know whats going on. They're trained to be curtious, sympathetic, but they realy have no solid answers about anything.

The facts:

- Many apple care associates have told me they know there is a problem.
- Some apple store techs have told me they know there is a problem
- Some of the apple savy techs at Fry's electronics told me they know there is a problem.
All of which have told me they have been getting complants from customers.

Another thing that show they realy dont have a clue: The apple experts at national apple care told me there is no difference between the Core 2 Duo (2009 build) drivers like for boot camp and the boot camp drivers for the i3. They are full of it. I have a copy of both and there is most definitely a difference in the drivers. Thats how I was able to fix the sound card and mouse problems in boot camp with the 2009 builds, by using some of the drivers frome the disk that came with the i3.

I'm looking at getting a refurb core 2 duo with 1TB so that is good news for me. thanks!
 
I bought my 27" Quad i5 a couple of weeks ago and it was silent then I turned it on a couple about the third or fourth time and it started making those banging noises.

I was about to take it back as i read a few stories here and on the Apple support site. But i thought i'd give going to Disk Utlility and repairing the HD option a try.

I didn't think it would work but (touches wood) it did and it now makes no noise again:D:D, so anyone out there who may not have tried it, give it a crack. It is by far the best machine I've ever had.
