i was reading this thread: http://www.linuxquestions.org/questions/history/361073
and i'm not sure what this means:
You cannot run fsck on a drive that is mounted. If you try to force this you can lose the entire partition. Unmount it before trying. You can mount it easily with full r/w permission, just set your -o flag in fstab to rw.
what's the -o flag in /etc/fstab? do they mean the mount -o flag?
