I know this Question has been answered in the past before but I forgot the procedure.

How do you fix a problem with the HD on startup again?

thanx

10.2 will check your HD on startup and fix any problems.

But I'm sure that depends on the problem.

hold down cmd+s on bootup to get into singleuser mode. once you are in single user mode run "fsck -y" until it finds no errors. then type "sync;sync;sync;reboot"

I've never been told by any literature anywhere to type the sync command before typing reboot. I have always just ran fsck -y until it came up clean then typed reboot. What does the sync command do anyhow?

sync & update

One of the reasons OS X is relatively stable is that Apple has implemented a periodic sync command in something called "update" - ran into it when I was exploring /etc/rc
