sudo zypper install 'nvme-cli' -y && sync
sudo apt install 'nvme-cli' -y && sync
sudo dnf install nvme-cli hdparm -y && sync

Suspend/Wake

  • Some motherboard firmware lock/freeze drives, and prevents some wipe commands from working
  • Unlocking drives can be done with a suspend and wake
  • :!: This applies to both SATA and NVMe drives
sync && systemctl suspend

lsblk

  • :!: Always check before running anything
  • :!: Assume nothing; all commands below are immediately destructive on the block device they're ran on
lsblk

EFI Variables

sudo rm -f '/sys/firmware/efi/efivars/'* || sync && sudo efibootmgr -v
