Disk Usage Very Strange

Just today, my Ubuntu 11.04 started prompting me that my HDD is full ... I know I am filling up my HDD fast, but its the storage partition I expect to be filling up not my 60+GB OS Partition. So I did a Disk Usage Analysis and got the below:

enter image description here

/labs is actually the Storage partition

First, my home folder /home/jiewmeng is said to use 58.8GB? but the biggest few files, don't appear to sum up to that? Counting quickly, it looks like ~1.5GB only?

Looking at the 2nd image, my HDD doesn't seem to be all that full at all? Is it a mistake?

UPDATE (df -Th output)

Filesystem    Type    Size  Used Avail Use% Mounted on

Run df -h in a terminal window. The output should have the proper numbers.

/dev/sda2              16G  5,1G   10G  34% /

udev                  2,0G  4,0K  2,0G   1% /dev

tmpfs                 807M  896K  806M   1% /run

none                  5,0M  8,0K  5,0M   1% /run/lock

none                  2,0G  224K  2,0G   1% /run/shm

/dev/sda6              28G   14G   14G  51% /home

In my example the /home filesystem is located on /dev/sda6 and has 14GB used (3rd column) and 14GB free space (4th).

You can check the total disk usage of a directory by using du -hs. E.g:

$ du -hs /home/username

14G /home/username

You may have hidden directories accumulating large files. The first yellow block in the gparted window shows that the root partition (/dev/sda1) is almost full.
