I am trying to zero out all the unused disk space in the FBSD system Hard Drive. Using this command dd if=/dev/zero of=filler bs=1m but get error message saying file system full and have file named filler. I don't think this commands is doing what I want. How can I check to see if the unused space is all zeros? Help please.
