I have the newest 12" iBook G4 and I had it ordered with the 60gig HDD. The drive is a Fujitsu and seems to be running fine yet I can't help but notice the almost cricket-like chirp it makes when accessing data..though it also makes the traditional HDD grind..it's not a loud chirp..but it is noticable. I backed up all my data just in case...but does anyone have a clue about what I am describing?
