After lots of experimenting, here is my recipe:
sudo fdisk -l /dev/sdasudo sgdisk /dev/sdsource -R /dev/sddest #will just copy the partition table-q1 sector by sector copy (might be necessary if getting error: “ntfs volume is scheduled for a check”)-icds (Skip check)-k NOT CREATE a partition table on destination diskgdisk /dev/sda # might have to run this from a live linux CDv (verify) and then w write back fixed GPT
