Hello, I am upgrading to a 1TB NVMe SSD and bought a special enclosure device to clone to it from my HDD. However, when I opened up the computer It looks like the previous owner installed a second HDD - it just says 1TB Seagate (Disk 0 in the image below). I pulled up Disk Management and it says my OS is intalled onto the Seagate HDD, but my boot drive is the main HDD (Disk 1 in the image below). Will I be able to clone like this? Do I need to clone from both drives? I was told by the previous owner that the extra HDD (the Seagate - Disk 0) does not need to be installed, and removing it won't hurt anything. I simply don't understand that - wouldn't I lose my operating system if I removed it? Thanks for any tips you can give me.
