Wipe A Computer

There are several ways to quickly wipe a computer, and there are a lot of reasons why you would want to do so. For instance, if you are selling a computer, recycling a computer, or simply throwing a computer away, then you do not want to contents of your hard drive to be accessible to anyone else. It could contain personal data such as photos, documents and financial records you do not want anyone to ever see. So you need to completely wipe the data from the drive, and do so in a way the data is no longer recoverable.

How To Quickly Wipe A Computer

One of the fastest and most secure programs to quickly wipe a computer is Darik’s Boot and Nuke (DBan).  This program has been around for years, but is still widely used because it works so well.  It not only erases the drive, but writes ones and zeros to the drive over and over, so the erased data cannot be recovered. To use DBaN, you will need to download it, burn it to a disk, boot to it, then press Enter to begin erasing.

How To Use The DBan Utility To Quickly Wipe A Computer

Download DBaN here, then burn the image to a CD or DVD. If you do not have .ISO burning tools, get one from our free software downloads site. Once you create the .ISO image, you can boot directly to the CD. Put the CD into the drive and restart the computer. If Windows loads, this means either the disk you created is not an .ISO image or your boot sequence in the BIOS is set to boot to the Hard Drive first. You will need to go into the BIOS setup ( Learn how to access your BIOS setup here) and set the CD ROM as the first boot device.

Or you can just put it on a floppy disk if you have one.

Once the DBaN utility loads, you will see the menu options in the diagram above. If you want to want to quickly erase any hard drives the utility finds, just type autonuke at the flashing prompt and the utility will get right to work.

Alternative Program To Quickly Wipe A Computer

You can use another program called KillDisk, which also quickly erases the hard drive. KillDisk is available in both a free and commercial version. The main difference between the free and commercial version is the ability to use US Department of Defense 5220.22 M (ECE) data deleting in the professional version, which means data will likely never be recoverable from the drive.

you can erase the hard drive using killdisk

The process is the same as for DBaN. Download, burn the .ISO, boot to the disk and press enter to begin wiping your drives.

Whichever program you use to wipe a computer, be sure to remove any external hard drives, thumb drive or other disks you do not want accidentally erased. This process is permanent, so make sure you have backups of whatever important data you want to save, as you will not be able to recover the data once the hard drive is wiped.
