    Wiping hard disks

    I've got 60 laptops to de-commission.

    Does anyone have a good (and quick) hard disk eraser?

    Preferably a boot CD so I can do it quickly without booting to the OS.

    You could try this:
    1. http://www.dban.org/about

    A single pass wipe will be fine.

    2. Download a Knoppix boot image and run the command dd if=/dev/zero of=/dev/hda <---sometimes it's /dev/sda

    3. http://www.ultimatebootcd.com/ This has got a whole heap of goodies (including a bunch of disk wipers)

    These two tools work great in unison:

    Tool 1

    Tool 2

    Then it's either physical damage to destroy the data or a hard drive degausser, which aren't cheap.

    When i wiped our old laptops here, i burned off 5 copies of DBAN and ran them over night.

    I use Kill and that's slow. Nature of the beast, I think. I've also used the this tool, which is fast and fun to use.

    It has to write to every byte on the disk, so it will take time. Have you chosen a single wipe? If so, best to set up a bunch of them to run overnight.

    Were they classroom laptops or staff laptops with potentially confidential data on them?

    Watch out with DBan - we used it to do some HDDs and data was still recoverable after the basic wipe.
