| ====== Nightwane ====== | ====== Information ====== |
| |
| ===== sda ===== | * Quick-commands to wipe drives and clear EFI variables |
| | * Notably performs full-drive TRIMs for SSDs ([[https://wiki.archlinux.org/title/Solid_state_drive/Memory_cell_clearing|ArchWiki]]) |
| | * Useful to perform before OS installations |
| |
| * If ''119.2G'', is Linux main | * Ideally use [[distros:opensuse_tumbleweed_gnome#xfce|openSUSE Tumbleweed's latest XFCE image]] on LiveUSB due to it having up-to-date tools, a GUI, and USB data persistence ((can copy a command into Terminal and run it on one machine, boot the drive on another machine, and use Terminal history to re-run the command; it's quite convenient :p)) |
| * If ''119.2G'', is SATA SSD | |
| |
| ===== sdb ===== | ====== Tools ====== |
| |
| * If ''931.5G'', is Windows storage | <code>sudo zypper install 'nvme-cli' -y && sync</code> |
| * If ''931.5G'', is SATA HDD | |
| * :!: Do not wipe this | |
| |
| ===== sdc ===== | <code>sudo apt install 'nvme-cli' -y && sync</code> |
| |
| * If ''465.8G'', is Windows main | <code>sudo dnf install nvme-cli hdparm -y && sync</code> |
| * If ''465.8G'', is SATA SSD | |
| |
| ==== Individual ==== | ====== Suspend/Wake ====== |
| |
| <code>sudo blkdiscard --verbose '/dev/sda'</code> | * 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>sudo hdparm --user-master u --security-set-pass 'x' '/dev/sda' && sudo hdparm --user-master u --security-erase 'x' '/dev/sda' && sync</code> | <code>sync && systemctl suspend</code> |
| |
| <code>sudo hdparm --user-master u --security-set-pass 'x' '/dev/sda' && sudo hdparm --user-master u --security-erase-enhanced 'x' '/dev/sda' && sync</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> | <code>sudo rm -f '/sys/firmware/efi/efivars/'* || sync && sudo efibootmgr -v</code> |
| |
| ====== Generic ====== | ====== Drive Wipe ====== |

| ===== Tools ===== | ===== Notes ===== |
| |
| <code>sudo zypper install 'nvme-cli' -y && sync</code> | ==== 4K Sectors ==== |
| |
| <code>sudo apt install 'nvme-cli' -y && sync</code> | * https://steamcommunity.com/discussions/forum/1/4739473745776804012/?tscn=1641033020#c3203747342915419588 |
| | * https://steamcommunity.com/discussions/forum/1/3203745634155479256 |
| | |
| | * :!: Steam and Oculus were **known** to be broken with 4K sector size on Windows 11 |
| | * Steam and Oculus work fine with 4K sector size on Windows 10 LTSC 2021 and Linux |
| | * iTunes possibly fails with 4K sectors due to Bonjour and dnssd.dll ([[https://www.techpowerup.com/forums/threads/setting-4k-sector-size-on-nvme-ssds-does-performance-actually-change.289757/page-3#post-4981622|thread]]) |
| |
| <code>sudo dnf install 'hdparm' -y && sync</code> | * See [[#sector_size]] to check or switch to available sector disk formats |
