Finding cruft

[Dazed_75]

On one of my machines I have two partitions for Ubuntu.  They are mounted
as / and /home.  I am getting a message saying the root filesystem is
nearly full.  When I run df -h, it shows me that /dev/sda5 is mounted as /
and had 13.5 GB of 14 GB used.  After I cleaned up some old kernels, unused
packages and a couple of other thing, it showed something like 11.5 GB of
14 GB used.

My question is:  What is the best way to find what else is overcrowding /?
In other words to do something like run du but restrict it to /dev/sda5.

Sorry, I am on a Windows system ATM.
