My wife and I just bought new iMacs from Amazon (direct from Amazon). Mine is the 27" model with the 3.1 processer. Her's is the 21" model. Mine is very loud all around, the super drive when starting up makes a very loud noise and even with a disc in it sounds very loud compared to hers. The more concerning thing is that my HDD is doing the much discussed "stomach gurgling". I checked this morning and it is the Segate 1TB drive (not eligible for the recall). Her's is a WDD 500GB and seems MUCH quieter compared to mine. I can still hear hers working but it's not the same gurgling as mine. I'm going to make a genius appointment but what should I ask them to do? Is there a standard WD 1TB HDD that they will put in iMacs or will it always be a Segate? Is it even worth taking in? It's kind of a hassel to get it all packed up. What is the turnaround time? Thanks for the help in advance, just a little frustrated.
