I have Ubuntu installed on my laptop.

cfdisk shows 150GB hard disk which is correct.

Baobab shows 56GB only.

Also, wherever I try to download something using Transmission torrent client it complains that disk space is not sufficient.

There is nothing on my disk except a few movies.

Where is all the space?

What does df -h say? – Ignacio Vazquez-Abrams Dec 30 '10 at 0:30

You could try $ sudo du -sh /* to get an overview of everything taking up space on your drive. It sounds like you might have partitioned your drive down to a 56GB volume, even if you don't have the other 94GB allocated to a different partition.

I tried this command it says 117G /home but I don't have 117G files anywhere. How do I join that 94GB to this 56G if that is the case? – Pratik Deoghare Dec 29 '10 at 21:46
Thank you very much for this command. I've been searching for this before. – Marwelln Dec 29 '10 at 22:23
@TheMachine: Go deeper in the search and run sudo du -sh /home/* to see more detailed info from that folder. – Marwelln Dec 29 '10 at 22:24

You can use utilities such as KDirStat to visualize where your free space went.

WinDirStat and Disk Inventory X are similar tools for Windows and Mac OS X, respectively.

And Baobab is the GNOME equivalent. – Ignacio Vazquez-Abrams Dec 30 '10 at 0:30

Did you make sure in installation that Ubuntu was set to use the whole disk and not a portion if it?

Check out your partitions by using gparted (sudo apt-get install gparted). Be very careful though. As noted elsewhere, gparted is a weapon of mass destruction.
