I'm selling a laptop that was used to handle my personal data, and want to wipe the SSD before getting rid of it. However, I just realized that my SSD doesn't support any of the Sanitize or Secure Erase NVMe commands.

How can I securely clear my data from the drive? I've heard that overwriting it with zeroes or random data isn't enough and is additionally terrible for the drive itself.

I'd post a picture of the output of nvme id-ctrl and my secure erase attempts but apparently I'm not allowed to do so as a new user.

If you are not selling it to a three-letter agency, and you don't have a specific fear of a nation-state learning the contents of the drive, you can simply overwrite once with zeros.

This will NOT protect the data with strong confidence, as there may be cells of the SSD that could still contain original data. However, it would take someone interested enough to work hard and spend money to recover the data on the drive.

The amount of money it would take is open for debate, but unless you are selling it to someone who is actively out to get you, you're probably fine, as they are most likely going to install an operating system and just use it.

Also, next time you set up a computer, make sure you encrypt the drive. That way you won't have this problem again.
