I am running ubuntu 12.04 64bit. I used the dd command to clone my 80gb drive (filesystem) to a clean 500gb. It worked flawlessly. Afterwards , I took out the 80gb and replaced it with the new 500gb. It boots up perfectly and the entire filesystem is as it was. However , when I right click inside a directory and click properties or when I tupe df -h , it shows that there is only 10gb free space. Howrver , in the disk utility it shows the 500gb as the filesystem and nothing seems wrong. How can I make ubuntu see that there is more than just 10gb free space on the new hdd ?
Here is the result I get in gparted and then also the contradictory result when right clicking in a directory and selecting properties:
