• Quick-commands to wipe drives and clear EFI variables
• Notably performs full-drive TRIMs for SSDs (ArchWiki)
• Useful to perform before OS installations

• Ideally use openSUSE Tumbleweed's latest GNOME Live image on USB due to it having up-to-date tools, a GUI, and USB data persistence ¹⁾

• 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

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

lsblk

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

• Steam and Oculus were known to be broken with 4K sector size on Windows 11
• Steam and Oculus worked fine with 4K sector size on Windows 10 LTSC 2021 and Linux
• iTunes possibly fails with 4K sectors due to Bonjour and dnssd.dll (thread)

• See sector_size to check or switch to available sector disk formats

• This is using LBA Format 1 for 4K sector size
