Hammer, then marinate for atleast 30 mins in soya sauce, onion, garlic, herbs, then bbq, eat and poop in 3 different bathrooms across the city. Pro tip, sprinkle with olive oil each side while on the grill.

Laughing at all the Hollywood shit in this thread. A single pass erase (or ATA Secure Erase, if they are SSDs that support the command) is more than enough. Nobody is going to waste time and money recovering data of unknown provenance from a landfill.

You’ve said you’re intending to throw these laptops away, so physical destruction is quickest and simplest.

But, if you’re intending to sell or give these away for someone else to use, zeroing each sector is probably ‘good enough’ for your purpose (as someone else has always said).

If you really want to make it harder, you can use something like the Boot and Nuke bootable Linux disk for the job, as it also has the option of multiple passes, using zeroing and/or binary random shit for each sector. Just grab the free for personal use version.

It depends how badly you need that data to never see the light of day again. Most likely, you’ll be fine to erase the drives with secure erase options (where it writes 0 and then 1 to the whole drive, and back and forth a few times depending on settings), but if you really really need to 100% guarantee there’s absolutely no chance of recovery, then you’ll need to destroy the drives physically
