I often have need to wipe hard drives before recycling them or reusing them. It’s very important to make sure any sensitive data is cleared from the hard drive so it isn’t easily retrievable. For years now, I have depended on Derik’s Boot and Nuke, better known as DBAN. I use it and make a bootable CD and bootable USB key so that I can quickly boot into the easily navigated software and wipe the data off the drive. You can configure multiple passes and a variety of wipe methods. I highly recommend this tool for every IT tech’s toolkit. You can find more information at https://dban.org/
