please see the bottom answer for my solution
After I use GParted to fix my partition(GParted ran well but my laptop shutt down because it ran out battery power and didn't finish the process copying my other partition, details),
I notice that I got 10GB increase in my Ubuntu partition, then I checked and found 1 suspicious file with size 140TB in /proc...
Is this a problem?
ubuntu 12.04 lts 64bit
I hope these details can help
sudo fdisk -l

I think the sudden increase 10GB in my Ubuntu partition is because unfinished GParted process, I currently have 27GB in used (when I right click in filesystem then check properties) , but disk analyzer says another thing(it says I am only using 12-13GB)
