I have just been using my Alu Macbook this morning and I've noticed the hard drive has started making little clicking noises. I know from experience that this is generally a bad sign, but for it to happen on a computer that isn't even a week old yet is a concern. It happens every 30 seconds or so and it makes a little "click". It sounds like its the drive doing something. It occurs even if the computer is on the desktop doing nothing. Any ideas? Surely this cannot be early signs of HDD failure already?
