Now, I know it is supposed to be clicking as that is normal described by all users of this tower, however, for the first week I didn't have internet access the clicking sound was a quick 2 clicks, now after upgrading to 10.4.4 when I got net access the click sounds a little different. I was worried it was the drive failing, but ran the hardware tool and it checks out fine, am I worrying about nothing? It only does it right when I turn on the powermac it seems, if that makes a difference?
If the drive does for some reason faail and need to be replaced is it something that the geniuses can do at the apple store with only a 1 or 2 day turnaround?
