Hi all, The internal drive in my 11 month old iMac alu died a couple of weeks ago, so I sent it into my local 3rd party Apple store. They sent it off to Apple and managed to replace the drive AND recover all my data, which I am immensely pleased about. However, I have noticed that the new drive seems to be significantly louder when it seeks. Unless this is my imagination, it used to be whisper quiet, whereas now I'm hearing rumbling "crrrrrr crrrrr" type noises whenever the disk is accessed. Has anyone else noticed differences in noise levels for iMac drives? Should I complain? I have a couple of weeks left of my warranty, and plan on buying 2 years of AppleCare.
