I was using Aperture and it just crashed, started going click, click, click. Which I believe is pretty standard. I replaced it, and it seems that something has come loose as it rattles when you shake it.
this happened to me. Take it into the Mac store. They plug in a separate hard drive and boot it up so that both hard drives show up on the computer. they move all the info you want from your computer to their separate thingy (real technical i know) and then you give them your computer for anywhere from 2 hours to a day, normally no longer, and they will replace your hard drive because that is probably what is clicking and then you probably have a pin somewhere loose which is what is rattling (that happened to me too, because I dropped my computer.) hope that helps? Oh and if you don't have it, normally they end up just giving you the newest system if they have to replace your hard drive.
