While /dev/urandom is probably "good enough" for this purpose, the effect is _not_ the same. That said, /dev/urandom is much easier and probably adequately secure for most people who need to wipe a disk. I would normally use /dev/urandom if I were in any kind of hurry. I figured that I might as well try this approach not only because the results would be somewhat better, but also for Sir Edmund Hillary's reason. I may not be such a fan of ketchup, but I just can't stand rhubarb pie. Attachment:
