Hi, im new to this but here goes.
Recently my harddisk (i think), has been making very odd noises. I suppose the thing spins so you could call it a spinning noise. It has never made this noise before and is very loud, you can hear it from the other side of the room. Is something going wrong internally, is the whole thing about to come crashing down around me!!
The noise mainly occurs when I access files, for instance when changing a song in iTunes the noise can be heard.
I can't really describe the noise much better than saying its 'like a spinning noise' - almost the same kinda of noise you get when your DVD drive is burning or something like that...

.. but worse.
Anyway, I hope all this made sense and someone can help me - because I'm really fretting! I have ALOT of work on this computer.
Thanks.
