For the quick method of erasing every hard drive plugged in, you'll want to press the F3 key. As you can see, the F2 and F4 options are informational only, so you don't have to be concerned about reading through them unless you have a RAID system set up (which probably isn't the case for most of you.you would probably know if so). There are your options from the DBAN menu: Or, you can choose the hard drives you want to erase, as well as select exactly how you want them to be deleted.
You can either enter a command at the bottom of the screen to immediately start erasing all the hard drives you have plugged into your computer, using a predefined set of instructions.
