Every time I restart this PowerBook G4 1.67, I'm welcomed by a hard-drive icon with a question mark in it, that flashes once, then proceeds to boot up properly. My HD condition is verified by disk utility, from the app and from the disk. I'm also running SMARTreporter 24/7 and it logs everything as fine. It has been doing this for about 3 months now but since I very rarely ever shut down or restart, it's never bothered me enough to report it. I have no issues with speed concerning a dodgy HD, I think this is more of a software issue where something somewhere has been misconfigured. Any help or solutions welcome.
