shred didn't shred
System is 64bit 12.04 Ubuntu. I recently used shred to get rid of several files, after which I ran photorec to see how the shredding fared. To my surprise, photorec recovered quite a few of the files I presumed were shredded. More may have been recoverable, but I stopped the process midstream. I used the following command: "shred -u -z -n15 [file name]", which I thought was overkill, but went for it anyway. Any ideas why the files persist?
