A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

Proper HDD clear process? (poptalk.scrubbles.tech)
submitted 11 months ago* (last edited 11 months ago) by [email protected] to c/[email protected]
 

Usually my process is very... hammer and drill related - but I have a family member who is interested in taking my latest batch of hard drives after I upgraded.

What are the best (linux) tools for the process? I'd like to run some tests to make sure they're good first and also do a full zero out of any data. (Used to be a raid if that matters)

Edit: Thanks all, process is officially started, will probably run for quite a while. Appreciate the advice!

# cat /dev/zero > /dev/your-disk

If you want progress bar, use pv instead of cat.

Or # dd if=/dev/zero of=/dev/your-disk status=progress
