DBAN, short for Darik’s Boot and Nuke, is a free program that allows the user to quickly and effectively delete all files on a hard drive. This goes for every single file, including the entire operating system.
Click here to visit its official website, and click on the Download button to start downloading DBAN. Once the ISO image is downloaded successfully, save it to somewhere that you can easily access. Step 2. Burn the DBAN ISO image to the USB flash drive.
It cannot see solid-state drives, and as a result, cannot format the data from this type of drive. DBAN works by physically overwriting each piece of data on the selected drive. Even the number one data recovery program can’t retrieve any of the data once DBAN has done its job. The files are completely irretrievable once processed.
Once DBAN runs in your BIOS, you’ll see a blue screen with a list of command options. Pressing the F2 key on your keyboard will take you to an informational page about the DBAN software. The F4 key will take you to the full DBAN disclaimer (RAID).
