At lease the quick test I just did makes me believe that using shred on ext4 might overwrite the previously used blocks. See bug #92271 to see what I did to quickly test it. But the problem with SSDs and similiar still exists. Besides that the FS should somehow promise, that it really has overwritten the old blocks (even if it hasn't really control about what the device does (if not using something like "Secure Trim"). -- You are receiving this mail because: You are watching the assignee of the bug.
