RE: Erasing a hard disk easily

hello

i've read that physically removing the disk plates
from a modern hard disk is more than enough to make
the information contained there imposible to read. the
servo information that is stored on each plate is very
sensitive to the relative position of the disks
themselves and the heads on the disk at the moment
that the disk is build so if you phisically remove the
disk plates from the spinddle it is almost imposible
to correctly align all the plates in order to
reconstruct the servo information needed in order to
make the "hard disk" work correctly...

saludos

Subject: [Full-disclosure] Erasing a hard disk
easily


I have a bunch of old computers I would like to
donate. Old laptops with win
95/98 on them and some old tower desktops all circa
1995-2k.
I would like to know if I can just use a magnet to
completely wipe out the
data for obvious security reasons. I have heard
about the disk erasers like
active kill and Perl utilities for this but with the
ability of data
ghosting etc. is this enough? Can I use a big magnet
like a speaker magnet
or something like a degasser to just wipe out the
data without having to
boot these old boxes and go through all the extra
work.

Thanks
