I’m unsure if this is a Linux specific issue but when I add or remove a hard drive steam will unlink family share which is a hassle to relink, I know it’s a niche question but does anyone know if reformatting a disk or partition will also cause an unlink? Thank you in advance.
I’ve had issues with family link staying linked on a steam deck with zero hardware changes, so it could be unrelated to your hardware changes fwiw.
