You didn't actually show any of the steps. My first suggestion is to use your favorite web search service to inquire how to remove an mdadm RAID1 array with a query like: "remove mdadm array".
Russell, I followed all the steps from <https://www.geekpills.com/operating-system/linux/remove-raid-linux> and while /dev/md0 was gone both /dev/sde1 and /dev/sdf1 were shown by lsblk to be part of the array. Turning off the MediaSonic Probox and letting it rest before turning it back on cleared the raid1 but pushed all disk letters in there further down the alphabet. Think I'll reboot and see if they return to sda through sdf. Thanks, Rich
