It could be a fan, so verify it is not coincidental with the fans going on. It could be your audio, so make sure it's not just coming from the speakers (though the fact that it occurs when you change the orientation of the PowerBook would tend to indicate it is something mechanical). If it's the disk, it would be an unlucky coincidence. There's nothing in the electronics or other operation of the PowerBook that would cause a mechanical fault in a disk drive. If your at all handy, you could replace the disk yourself; it's pretty easy to do. AppleCare did let me do so once last year, sending me a replacement with a return shipping label to send back the bad one. You'll have to give them a credit card number as a cancelable deposit. -- Dennis Fazio dfz at mac.com
