Selling your computer but worried of somebody trying to
get a hold of your personal information? As some of you
know, whenever a file is deleted from the computer, it
does not really gets deleted but rather the opearting
system identifies the space as available so it can be
re-recorded again. This is a huge problem since your hard
drive can fall in the wrong hands. In this article I will cover
my favorite method for wiping a hard drive clean, a
method that is reliable and can even be run under
Windows using Virtualbox.

There is a free program for this purpose which
everybody seems to prefer, however, I do not. That
program is Darik’s Boot and Nuke (DBan).
Dban
seems to have terrible USB detection capabilities.
Fortunately, there is a better solution. Parted Magic offers
you several options. Some are meant to be a quick solutions and some like nwipe (a fork of dban) are
for the paranoid. However, all of these options will make your data unrecoverable, regardless of the
one you pick.
Using USB vs. SATA Controller
It is important to mention that, as convenient as connecting your hard drive by USB is, it is always
faster to connect the hard drive directly using either the computer’s SATA or IDE cables. Bear this in
mind before starting to wipe a large hard drive, or you might end up waiting days rather than hours.
WARNING!
: When working with any of these programs, make sure you have the correct hard drive
selected. Once you wipe the hard drive with any of these methods, your data will be unrecoverable!

your computer’s BIOS.

Using Dd disk, Ddpart, Shred or Secure Erase Command
Dd disk, Ddpart, Shred and the Secure Erase command are all meant to be quick solutions. If you are
in a hurry to wipe your hard drive and don’t want to wait several hours, these are the solutions for
you. They are safe enough to keep your data out of the average “wrong hands” but they are not as
secure as nwipe, which I will be discussing in the next section. However, going into which method is
more secure over another is not the purpose of this article. If you would like to know more about how
these methods work, read
this article
by Peter Gunntman, the leading authority in the field.
The instructions to start Dd disk, Dd part, Shred and the Secure Erase Command are pretty much the
same. The following set of instructions apply to all except nwipe. For instructions on how to use nwipe,
go to the next section.
Once you have the “
Disk Erasing 101
” menu open, select any of the methods previously discussed
and click “
Continue
“.
On the next window, select the drive you will be wiping. Be 100% sure of the selection you make, or
you will probably end up wiping a different drive. Once the wiping process is started there is no going
back; your data will be lost. Click “
OK
” to continue.

Next, you will receive a warning asking if you are really sure of what you are doing, if you are, click
“
OK
“.
The wiping process will begin immediately after clicking “
OK
” without any further warning.
Nwipe Instructions
If you are truly paranoid about the data you have in your hard drive, Nwipe will give some peace of
mind. Nwipe uses the most advanced and secure wiping techniques. It is a fork of the famous Dban
and offers pretty much the same capabilities.
Contrary to the previous options we just discussed, Nwipe requires an existing accessible and readable

partition, otherwise the drive will not be detected. Parted Magic must be able to see and access the
drive. If the drive does not have a filesystem, Nwipe will not detect it. To check this you can either click
on the icon named “
Mount Devices
” and see if it comes out on the list of devices to be mounted, or
click on “
My Documents
” and see if it appears on the left hand side column.
To open Nwipe, select it from the “
Disk Erasing 101
” menu and click “
Continue
