Error while starting Ubuntu

Yesterday, when I was starting up my Ubuntu machine, the screen went white and I had to manually turn off the laptop.
When I started it again the file system checkup (fsck) started. I got a lot of yes or no questions about fixing several problems. Near the end fsck aborted and I was left in the terminal to try and fix the problem.
I rebooted the system, but there was a X server error and it went to the terminal again.

Ok, at this moment I was scared. A lot of data I didn't wanna lose.

I logged to my desktop machine and went to Ubuntu Forums.

Here's what I did, and yes, I'm posting from Ubuntu:

• I started by unmounting all my file systems:
  

sudo umount /dev/sda1
sudo umount /dev/sda5
sudo umount /dev/sda6
sudo umount /dev/sda7


• Then I run a filesystem check, like this:

sudo e2fsck -C0 -p -f -v /dev/hda1
sudo e2fsck -C0 -p -f -v /dev/hda5
sudo e2fsck -C0 -p -f -v /dev/hda6
sudo e2fsck -C0 -p -f -v /dev/hda7


And that was it :-)

I rebooted and all was ok.
