On my personal file server PC, I have two 1TB drives that are configured in Windows Storage Spaces to be I'm assuming a RAID1 array. Basically my two 1TB drives show up as one 1TB drive. Eventually I am going to replace Windows 10 with Server 2016 (which is on a separate SSD) and I wanted to make sure I didn't corrupt the array, or whatever it is with Storage Spaces, when I reinstall Window. I thought about just unplugging the drives while I reinstall, but I wasn't sure if this will still cause issues. So do I need to do anything to prevent issues, or can I reinstall Windows without worry. If I do need to do something: backup data; clear the Storage Space setup and anything else?
