'shred' is part of coreutils (i.e. installed by default).
Doing something like
shred /dev/sdX
as root will write various bit patterns 25 times over the entire drive
(see the man page for more options).
Whoopeeedoo. Thats still not the correct way to erase a disk.
Use security erase, that is why it is there.
I use a hammer, because it wins over all other solutions on both ease
of use and catharsis.
For laptop (1.8" and 2.5") disks, sure. A couple of good bangs and you have
yourself a maraca.
I haven't so far been able to destroy 3.5" disks with a hammer, as the
enclosure is quite durable. A sledgehammer would probably do the trick. Or,
you can open up the hard drive and smash the magnetic disks.
I use some of the undocumented options to /usr/sbin/hammer that are
relevant to larger disks:
hammer --unscrewfirst|-u
disassemble the drive using a tork wrench first before smashing
the platters
hammer --force|-f
use more force with the hammer
NOTE: use of -u and -f together is discouraged unless wearing suitable
protective equipment.
I generally take the drives out to the desert and use /sbin/detonate.
As Jamie Hyneman once said on "Mythbusters"...
When in doubt....C4!
