The "security erase" feature mentioned above is not the "paranoid % security erase" that some external applications do. It runs only once, % and the most important detail is that it is done by the disk firmware, % not the host computer CPU. Thus what it actually does depends on the % disk manufacturer. [snip] Oh! Thanks for the clarification; I didn't realize that. Although I am the type who runs a script to write zeroes (easy), ones (easy with a quick NOT), and randoms (alas, /dev/random takes a while) repeatedly for as long as the machine happens to stay up :-) before it gets taken away, it's good to know the difference.
