Just make sure you get the right drive you don’t want to try wiping your primary drive or any other important information.įor those reading this who don’t know why you would want to securely delete your files, here’s the rationale: just deleting files on a hard drive doesn’t mean someone can’t recover them. You can figure this out by looking in the “dev” folder or by using gparted. If you’re wiping an external drive, you just need to know the letter of the drive, and can then swap that out in the command (e.g., “/dev/hdc” or “/dev/hds”).

It’s basically like booting using the live disc, but the sole purpose of DBAN is to wipe the drive.

There is, apparently, a disc image you can download that makes wiping the primary drive quite easy: Darik’s Boot and Nuke or DBAN. Otherwise, the primary hard drive will be from where the operating system is running,which means you won’t be able to issue the command. If you are wiping your primary drive, you’ll need to boot into Ubuntu (or some other brand of Linux) using a live disc then open a terminal and type the above command.

Finally, the “/dev/hda” portion of the command tells the computer which drive to wipe. Writing over your data 100 times is likely overkill 3 to 5 times is how many times I typically wrote over data using Eraser (which does the same thing).

The more times you write over the data you had on the drive, the lower the odds that someone will be able to recover your files. This tells the operating system how many times to write random data to the drive. The “-n” command is followed by a number (“100” in the example above). The “z” in the “-vfz” command writes zeros to the drive. The “f” in the “-vfz” command forces the write by changing the permissions on the drive wherever necessary. “shred” is the command that tells the operating system that you want to not only erase all the files on the drive but also to over-write those files with random bits. Here’s an example of the command with an explanation following: Turns out, however, that this functionality is built into the operating system, though it is command-line only. I looked for a while for something similar for Ubuntu Linux but couldn’t find any programs like Eraser.
