Hi,

I recall there is a magic dd incantation that will wipe out both the original gpt partition table and the backup at the end of the drive so I don't have to write /dev/zero to every block on the drive if I want to start over and repartition my encrypted drive.

Unfortunately my Google-fu has failed me. Would someone mind giving me a nudge to how I can whack the drive quickly and start over again? I get that the old data will still be there unless I wipe it but I'm just messing around to figure out how I eventually want to config this machine (Thinkpad T440p with Coreboot/Tianocore).

Thanks!
