Repaird Fedora 12 File System

Last time when i start my Laptop it was normally booted & worked well. while the working i saw there are several updates are available for fedora 12 so opened the terminal and logged as root. then run update command by giving
yum update -y
it start to update. during the update process is downloading updates just minimized it and worked same as normal. there are no unusual things happened that day.

but day after that day i start my laptop i it wouldn't boot
it gave following message & i gave root password for it.

*** An error occurred during the file system check.
*** Dropping you to a shell: the system will reboot
*** When you leave the shell.
Give root password for maintenance
(or type Control-D to continue):
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell
(Repair filesystem) 1#


first i tried several times by pressing CONTROL-D. it restarted & gave same message
after that i found the problem it needs repair the file system. so i gave following command to repair file system (sda5)

fsck -t ext3 /dev/sda5

it takes a little time to repair file system

that's all after rebooting the laptop it was successfully booted to gnome desktop.

finally i got my desktop back
yepieeeeeee!
