by swap them around i mean physically take the two drives out and put them in each others connectors. by interface i mean physical interface, like the plug or socket or slot they connect to the motherboard with.
the bios usually enumerates drives based on their position on the bus, so switching the connector they’re plugged into would fix the problem.
linux usually handles drives based on uuid, a unique identifier per device, so it wouldn’t mess up linux.
you didn’t specify if one was like a sata or esata or nvme and the other was different so i had to qualify “if theyre the same interface”.
why do you want to learn a gui for firewalld?
almost all the support and documentation is gonna be using the cli command firewall-cmd.
