So I'm assuming the world is about to end, or at least on my hard drive, but I wanted to see if anyone has encountered this before: Sometimes when I try to open an app (Abode CS seems to be the worst) it pauses for up to 20sec until I hear a single loud 'click' from my hard drive and then it seems to load ok after that. Other times it will make the same noise when the OS is trying to access it. Seems to be after the disk has't been accessed in a while maybe? I have HD sleep option turned OFF in energy savings prefs. It's an older drive that came with the G4 733, so I've been trying to back things up and prepare for the worst. I'm running 10.3.7, but I don't think its related to the update. Thanks!
