I suggest to "mdadm --fail" one drive, then "mdadm --remove" it. After

Does it make sense to dd or ddrescue from the removed drive to the
replacement? My md RAID set is on primary partitions, not raw drives, so
I'm assuming the replacement drive needs at least the boot sector from the
old drive to copy the partition data.
