Ubuntu 10.4 LTS Encrypted Hard-drive
I recently deleted about 30 GB of files from a folder on my Desktop. After restarting however, I found that, while I cannot find the files anywhere, my computer tells me that I only have 600MiB free/Available Space.
System Monitor tells me that I have 92GiB Total, 86GiB Used, 5GiB Free and 667MiB Available (using the command df confirms this)
While Disk Usage tells me when I scan the Filesystem that it is 53GiB size, with 667MiB Available.
Why are they telling me different disk usage numbers, and how do I completely erase the 30G of files so as to get more free space? Thanks!
