It looks as though my HD is going bad. For about a couple of weeks now I've noticed that if my iBook (G3) is on for a long period it'll start making this clicking sound and eventually thereafter hang. The only solution being to let it cool down and reboot. Well, Friday it started saying that it lacked space on the startup disk although I had over 2 gigs. Today, it took much longer than usual to boot and applications are taking a long time to launch. So I ventured into the logs and there I see in the system.log: kernel: disk0s3: I/O error disk0s3 is mounted as the root directory and I have no other disks on the system really. (there are 2 /dev and a /.vol, /Network, /automount, ...) which is repeating about every 30 secs. Looking back in the logs however, I couldn't find any other such errors except for today. But then I only went back about a week. I have backed up most everything, so I am not worried about whether I lose the HD or not, but I would hope to save it somehow. What are my options? Seems like there's a boot disk solution. That is, insert the boot disk and enter a command console and from there do something like fsk.
