From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

dd if=/dev/zero of=/dev/(your drive)
You can do status=progress if you want like someone else posted and if you pick a block size go with either the physical block size reported by the disk in smartcontrol or some multiple of it that coincides with a big even division of your controllers memory. The drives physical block size will be “easy” for the drive, bigger blocks are faster.
People saying physical destruction are operating in a different world than you and people saying urandom or shred are operating off old (>30 years) information. The same technology that makes ssds unrecoverable black boxes was originally developed and deployed in spinning drives to eek out speed gains because the disk itself can be expected to know better than the operating system where to put shit and makes techniques (which were postulated but never actually implemented successfully in the wild) to recover overwritten data infeasible.
Alternately just reformat it and don’t worry. No one doing drive rmas cares about your data. They’re already on the razors edge with feedback and customer trust, you think they’re gonna burn their above board bread and butter to run a harvesting operation for a few bucks on the side? That’s usually the purview of your local pc repair shop…
