How I fsck'ed Serenity

Serenity, my trusty Apple iBook, is never turned off. I close the lid and it goes to sleep. When I need to use it, just open the lid and in about 2 seconds, it's ready for me. So every month or so, I'd do some system maintenance on Serenity because prevention is better than cure. I usually use Onyx to automate the task, but the latest version of Onyx does a disk verification at startup. So during this disk verification, it found some errors on my harddisk!

To be extra sure, I ran Disk Utility's Verify Disk and sure enough, errors were detected on my harddisk and to repair, I had to boot Serenity with the Tiger DVD. Since I didn't have my Tiger DVD handy, I did the next best thing. I decided to fsck (file system check) Serenity.

I don't know the technical details behind fsck, but I knew I had to run it to fix the errors. fsck has to be run at the Console at startup. So I rebooted Serenity and pressed Command+S until some Linux-y text appeared on the screen.

There were instructions on the screen on how to run fsck, and since my harddisk is Journaled, I had to "force" fsck, so I entered at the prompt: fsck -fy

I had to keep typing fsck -fy until the message states that the harddisk does not appear to have any errors. Fortunately for me, I only had to do it twice.

Then type exit and press Enter to resume booting into the OS. Everything looked OK until I found out my trackpad wasn't working, my Bluetooth and WiFi was non-existent! Resisting the urge to scream like a wussy, I decided to try restarting Serenity. Luckily the keyboard was still working and managed to reboot Serenity.

A reboot later, and everything was back to normal. Phew...

And folks, that's how I fsck'ed Serenity.
