Is > writing a null gpt sufficient? For software disk management (md, LVM, ZFS, etc.), whether to use entire disks or to use partitions is a matter of preference. Some people like to use entire disks to skip layers of drivers (e.g. minimum latency, minimum memory), to obtain 100% of the available blocks, etc.. Other people like to use partitions to apply meaningful labels to the partitions, to choose a somewhat smaller size to accommodate disks with different numbers of blocks (important when replacing a failing drive), etc.. For a mirror of two identical disk drives, I chose md RAID1 and entire disks in 2017. KISS. I think that would work for you now. You will not need the ext4 file systems. Whether you choose partitions or entire disks, it is good to zero-fill them prior to giving them to your disk management software. But, zero-filling disks and partitions is dangerous due to the risk of operator error. I use a spare computer with no drives other than the drive in question. I boot d-i, Debian live, a personal live USB stick, etc., and do the work. If I make a mistake, I will not trash a production computer. David
