Have a poke around for hidden ".trash" folders, particularly on mounted media such as USB/Firewire hard drives. I have found that Ubuntu has a habit of creating these on such volumes and they do not appear to get emptied by the usual processes. I have often thought I had deleted files then realised that my disc space had not increased as a result, it was always a hidden trash file that was the culprit. Manually deleting the files from the trash files usually gets rid of them.
It may be the large volume you have at /media? that is hiding such a file. I'm not sure why that "hidden" data wiuld not be seen by df and du though?

Subject: [ubuntu-uk] df and du give different results
I'm running a Dapper webserver and I'm having terrible problems with
du and df giving different results:
df -h gives me.....
Filesystem Size Used Avail Use% Mounted on
29G 27G 347M 99% /
varrun 252M 52K 252M 1% /var/run
varlock 252M 4.0K 252M 1% /var/lock
udev 252M 52K 252M 1% /dev
devshm 252M 0 252M 0% /dev/shm
1.4T 710G 671G 52% /media/netbackup
/dev/sda5 228M 14M 203M 7% /boot
sudo du -hs /* gives me.....
Now that just doesn't add up.
I wondered if it might be a problem with open files, so I've tried
lsof | grep deleted and lsof | grep DEL
They showed Apache2 and MySQL had some files open so I restarted them.
This didn't help so I restarted the server. Still no joy!!
Please help me :-O
