You can boot of your install media and repair the drive from there. Or boot holding down command + s and boot in to single user mode then run:

fsck -yf
 
What is fsck? How do I do this? The Apple support page is confusing but it says for my problem, to ignore it and use single-user mode and run it. I dont understand. If I am the only account on my computer, am I in single user mode?

You can also boot from installation disk. Keep pressing 'c' after hear boot sound till screen is starting.
run disk utility and repair the volume.

Thanks, I will do that. I just don't like restarting my iBook two times in 10 minutes... I feel like it abuses it or something, does it cause any harm? Also because I shut down last week after the security update.... I feel its been going on and off too much.

Like I said above you hold down command + s when you boot to get in to single user mode. It will drop you at the OS X command line, you then type

fsck -yf

It will do its magic and fix any hard drive errors it finds, you then mount the root drive by typing

mount -uw /

you can then reboot the machine by typing

reboot

and you're done.
