Just need a second opinion. The HDD in my 12" Powerbook G4 is starting to vibrate, a lot. The noise comes and goes, and changes based on the orientation of the laptop. I know it isn't the fan, because I hear it throttle up and down independent of the vibration. Before I shell out $120 for an new HDD and go spelunking in my laptop (a difficult operation), I'd like to image my whole HDD on an external temporary drive for safekeeping. Then after I install the new HDD, copy the image over without reinstalling anything. If this is not possible or there are better ways of going about it, I'd like to know before I start.
