Destroying HD data (physically)

    I'm aware of the command dd (dd if=/dev/zero of=/dev/rdsk/c0t3d0s2
    bs=1024k) to overwrites data on a disk, however, before I can do dd
    some of the drives crashed (head?). My question is, how do I destroy
    the data on the disk when the head crashed? I don't want the data on
    the disk to exists, but without the ability to hook it up, I need to
    resorts to physical destruction?

    Nail the drive to a post and use it as target practice for your AK-47.

    Take the cover off, throw in a liberal amount of sand, put the cover
    back on, and power it up.

    Then run over it with your truck.

    I have no handguns, semi-autos or WMD :) to destroy the drives.
    I thought about opening the drives to destroy the platters, but
    the screws are tough to loosen. (these are SCSI drives btw)

    Well, if the OP has no nails or AK-47 he could remove the platters from
    the drive and sand the rust off them. That should introduce a sufficient
    amount of entropy that data recovery would be impossible.

    Have it hung, electrocuted, shot, and drowned. Then chop it up into
    little bits, and then jump on them. And keep jumping until you get
    blisters, or you can think of something worse to do.

    After a head crash, the only way to destroy the drive further is to
    install Linux on it.

    David, the OP said he could not hook up the drive. Nailing is pretty
    close ;-)

    A Torx-8 driver is usually required. But if you lack one of those a big,
    hot bonfire would probably do the job. A 12 lb. sledgehammer would
    work also. A sharp cold chisel between the cover and housing will cut the

    Use your imagination. Be destructive!

    New series of Hitchhikers on BBC Radio 4 starting Tuesday this week at
    18:30 BST, repeated Thursday 23:00 BST. Starring many old cast-members
    plus the excellent Michael Fenton Stevens and the delightful Joanna Lumley.

    Just use what you have to get into the drives. Drilling a couple
    of holes through the platter pack will do pretty well.

    A hacksaw can be used to open.

    The standard trick is to drill off the screw tops. The Torx
    heads are nice - there are starter holes so the drill keeps
    on the screw.

  14. AFAIK, burning the drive detaches the magnetic layer from the
    substrate, rendering it quite unreadable. So have a BBQ, and grill your
    data. Other idea would be to hook it up to a MIG/TIG welder, and put
    some real current through it.

    When I had my first security briefing for a UK defence project, I was
    told that all hard disks on the project were the property of the MoD
    and that once we were done with them they had to be shipped off to be
    disassembled and the platters had to be boiled in acid. That seems
    like it would take care of it.

    If the OP wants to do a Google search, he can probably find "The
    Anarchist's Cookbook" (or some such) that has 'recipes' for various
    incendiary concoctions.

    Though it should probably be noted that the local law enforcement
    officers may be entirely pleased in these methods of 'secure
    deletion'. :>

    I still like the idea of using the drive as target practice. But to be
    certain of destruction tossing the drive onto the feed conveyor of a
    blast furnace would also be quite effective. Heck, the magnetic media
    would then produce a few milligrams of pig iron :)

    Thank you all for your creative suggestions. However, I have a drill
    (and a steel drilling bit) and decided to drill a hole in the drive,
    pour salt (epsom, and tape the hole), plug-in the drive for a few
    minutes. Next, I pour some water in the hole, re-plug it, tossed the
    HDs into the river (I figured if this river is good enough for the mob
    to dumped their evidences, it's good enough for my HDs/data). Besides
    my HDs would sink to the bottom and not float after a while :)

    The data is nothing malicious, just username/password/SS#/etc. and I
    hate for someone to tinker with the bad drives and retrieve the info.

  20. Just so long as the "cook" keeps in mind that some of those
    concoctions are more dangerous to the cook than the misbehaving hard

    Trying to type with a hook instead of fingers might be a tad
