Wipe a disc clean

People are under the misconception that Formatting a drive wipes it clean, think again it does not, this is what the data thieves rely upon.

The way which you can be sure about is :- Darik’s Boot and Nuke, (DBAN).

1. Download the free DBAN software from their website. It downloads as an ISO file.

2.. Before you start ensure that all the data you want to keep is backed up and copied to another source, because once this process is complete, you will not be able to recover any data from this hard drive

3. When you Download you need to burn this image to a CD-R or DVD-R. It is important that you burn it as an image, and not simply burn it to a disc.

To do this on Windows 7, right-click on the DBAN ISO file and select Burn disc image.

Now click Burn to start the burn process.

If you are using XP or Vista, you will first need to download an ISO burn utility. You can find a free one here:- []

Once installed, you just right-click on the DBAN ISO file and click Copy image to CD.

4. Now that you have Darik’s Boot and Nuke on disc, you need to restart your computer and make it boot from your CD/DVD drive.

Instructions on how to do this will vary depending on the manufacturer of your computer, but it usually involves pressing a function key during the boot up screen so that you can enter the BIOS settings screen and change the boot options to boot from the CD/DVD drive instead of the hard drive as it will be set to do by default.

Dell users should hit F12 a few times as soon as the computer restarts in order to get quick access to the one-time boot menu that will allow you to select the CD/DVD drive as a bootable option.

5. As soon as DBAN loads from the disk you created, you will be greeted with the options menu.

For a default wipe, type autonuke and press Enter. This will begin the wiping process.

However, by pressing simply pressing Enter it will give you more options and allow you to choose what level of security you wish to employ in your data wipe.

6. Select the drive that you want to wipe and then type M.

7. Next select from the security options you are given.

The DoD options are the standards used by the Department of Defense. The most secure option is the Gutmann Wipe, but this is also the longest method. i.e. takes a long time to wipe.

DBAN recommend the last option, the PRNG Stream wipe as sufficient for most users, but the choice is yours. The spacebar will confirm your selection.

8. Make sure that the drive you want to wipe is still selected, then press F10 to start the erasing process.

9. The time required to complete the task will depend on the size of your disk, the amount of data on it, and the security method you chose.

It can take several hours to complete, but the peace of mind that follows knowing that nobody will ever be able to recover any of your data from this hard drive ever is well worth the time.
