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.

Thankfully it is largely just a few commands with built in tools to tell the drive firmware to secure erase

This. And then when it's done, use a hex editor and look at the raw disk to make sure it actually worked. Some manufacturers don't implement it properly.
Sorry, but can you explain a little, how this is done exactly? What should I see, when everything worked correctly?
Preferably all zeroes, possibly random data or a fixed string. Certainly not anything readable.
No, you don't want all zeroesz, you want random data.
Within Linux you can quite easily do this yourself too
It's fine for SSDs it does not have the magnetic residence where you could recreate data.
I just shove them into a grinder...
According to the upvotes, this seems to be the way. I will try that, thank you!
