Now this is a fun little app! We had some old boxes in the office that needing nuking before taking them off to be recycled and I remembered I’d seen a post on LifeHacker a while back on it.
It’s incredibly simple to use. You’ve got a few options as to how to run it, but I just downloaded the .ISO file from SourceForge and burnt it to CD. With that I was able to boot the machines directly into DBAN and nuke the drives.
There’s nothing flash to it, it’s purely functional. It’s running a cut down Linux kernel which looks like an old DOS app. You’ve got various options for what level of write you want, but I just went with DoD Short since it was relatively quick at an hour per machine.
