I recycle ewaste, and so I have boxes and boxes of old hard drives. My proc is single pass dban and then a 10mm hole drilled through the case and onto the platters.
This is for normal business eol hardware that I get from offices and warehouses, nothing sketchy.
If the client wants evidence of destruction before leaving premises, I skip DBAN and just drill the platters with a cordless drill.




















These days it’s more likely a Facebook post that hurt their govt’s fee-fees or a torrent of a shitty TV show
