I am using Debian Wheezy, I get constant notifications: 0 bytes left (i cannot download anything, so notifications are not erraneous). Disk Usage Analyzer shows only 13.2GB of files. Gparted shows 224GB used and 54GB free (Root Partition). After I live booted with Ubuntu14.04, I checked the properties of the partition, which showed Total Contents:13GB only, but again Gparted gave same results. I have also encountered the nautilus bug, which caused the kcore file in /proc to show as 140.7TB. (reboot won't help at all).
Result of df -h:
