[clue] secure erase techniques?

[Randy Evered]

At the installfest I used badblocks under a PuppyLinux Live CD to wipe a
drive:

   badblocks -svw /dev/hda

Then stop it after one full pass of writing.  It is used to check a hard
drive is good.  You can also tell it what pattern to start with (i.e. 0x00).
