| ====== Tools ====== | |
| |
| <code>sudo zypper install 'nvme-cli' -y && sync</code> | |
| |
| <code>sudo apt install 'nvme-cli' -y && sync</code> | |
| |
| <code>sudo dnf install nvme-cli hdparm -y && sync</code> | |
| |
| ====== 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 | |
| |
| <code>sync && systemctl suspend</code> | |
| |
| ====== lsblk ====== | |
| |
| * :!: **Always** check before running anything | |
| * :!: Assume nothing; all commands below are **immediately destructive** on the block device they're ran on | |
| |
| <code>lsblk</code> | |
| |
| ====== EFI Variables ====== | |
| |
| **** | |
| |
| <code>sudo rm -f '/sys/firmware/efi/efivars/'* || sync && sudo efibootmgr -v</code> | |

| ====== Drive Wipe ====== | |
