What's the Best Way to Securely Wipe an NVMe Drive Before Selling?
Asked by

I'm looking to sell my laptop that has an NVMe drive, and I want to ensure that none of my personal information is recoverable. I have disk encryption set up, but I'm feeling a bit paranoid—especially since I used a weak password that has been exposed in leaks. Ideally, I want an effective way to zero out every byte on the disk. I remember hearing in the past about overwriting hard drives multiple times, but I'm wondering if that advice still applies to NVMe drives. What methods would you recommend?

You have a couple of solid options for securely wiping an NVMe drive:
1. **Secure Erase:** Check your BIOS for a secure erase feature that can wipe your SSD. It’s usually safe, but just ensure you trust your SSD’s implementation because you won’t be able to verify the wipe.
2. **Dedicated Software:** Use reliable hard drive wiping software. Many options can do a thorough job of zeroing out the disk, which should give you peace of mind. While it seems like big organizations could recover your data, for personal use, a decent wipe is usually adequate.
Just remember, don’t let the perfect be the enemy of the good!

For a quick and simple solution, you can use `blkdiscard` to erase the drive. But if you're passing it off to someone, I recommend using `nvme-cli` with the `format` or `sanitize` options. This method makes sure any internal data and cache are cleared—it's really efficient! I don’t get why people still talk about mechanical drives; SSDs are much easier to wipe these days!
ParanoidPanda7: Thanks for the info! The `nvme-cli` method sounds straightforward. Do you think just a single format is enough for these drives?

Honestly, some people are getting it all wrong! For NVMe drives, just doing a secure erase or `nvme-cli` is enough. Forget about crushing or microwaving it—that's a bit overboard!

NervousNelly34: I'm just worried about residual data like passwords or cookies being recoverable, especially if software isn't well-implemented. How does the secure erase feature actually work? Does it effectively zero everything for NVMEs?
