I am a Ubuntu beginner and I started to use Ubuntu 12.10 beta 2 last week. I found that my hard disk is full. It seems the disk does not mounted correctly. However, I have tried a lot of codes but they don't work at all. Thanks for your help.

 peng@peng-ThinkPad-SL410:~$ df
文件系统           1K-块      已用    可用     已用%  挂载点

none              102400        36  102364    1%   /run/user

Translation:
文件系统 = File system
1K-块 = 1-K Blocks
已用 = Has been used
可用 = Available
已用% = Use %
挂载点 = Mount point

There are several tools that can display your disk usage graphically, for example filelight. Without futher investigation, it is nearly impossible to say what causes your disk to get full. If you get that additional info, you should post that in your question to get more precise answers.

For me, the downloaded packages (.deb files) are often a source of high disk usage and you can clear that using the command apt-get clean.

And like the other answers state, I can't see why your disk shouldn't be mounted correctly.

I have a few questions first. What makes you think that the disk is not mounted correctly? Is your hard disk's 240 gb or is it very different?

Assuming its a file or bunch of files which might have caused this, you can try du -sh / in terminal to see which folders are abnormally large and then run the command on that folder and so on to track down the offending files if any

You can investigate the problem with the Disk Usage Analyzer. It wil show a graphical representation of the size of files and directories on your hard drive and you can quickly drill down to the problem areas.

I see no indication that your partition is mounted incorrectly, unless you have more partitions on your hard drive that should have been mounted as well. The following command gives a list of partitions, which may help us to identify the problem:

sudo parted /dev/sda print

I had a similar problem and it turned out a log file was getting massive.

Change to your Home directory:

cd /home/*yourusername*

ls -al 

check to see if anything is way too big. My .xsession-errors file was 430GB!

So I deleted the darn thing:

sudo rm .xsession-errors
