How to run a manual file system check?

**tinker123** · May 25th, 2008

Hi;

Something happened while I was booting my Ubuntu 8.04 box. Now, every time I boot it tells me that a fcsk of my hard drive failed and that I need to run a manual file system check to make that message go away.

FWIW, I think it would helpful to include direction how to do that with that message.

Anyway, what do I need to do to make that message go away?

Thanks in advance

From a live CD, run

Code:

sudo /sbin/fdisk -l

You will get a table, with first column "Device" and last column "System". For all devices that have System "Linux" (not "Linux swap" or something else), run the following after replacing <device>

Code:

sudo /sbin/e2fsck -c -f <device>

This will take quite long as I have included the -c option which will check the hard disk for bad blocks. I did this because some thing more than usual is wrong with your system, this is worthwhile for you.

Or just before you shutdown or restart use

Code:

sudo touch /forcefsck

At the next boot the system will do a check of all system partitions, including home if it is on a separate partition.
