steps to take in r-Studio : virtual volume or virtual mirror ?

[FSHEHTESI]

yesterday 1 drive of my mirror drives in Storage Spaces in windows 10 (refs filesystem) was damaged. So I disconnected both drives , the damaged one and the good one. After that I deleted the group in the Storage Spaces. But now when I connect again the good working drive , it mentions in disc management ‘non allocated space’. So I want to have the good working drive again normally. I can already see the virtual volume but I can also see a virtual mirror . I created both virtual systems because I do not know what to choose . But which exactly do I need to scan and what sections do I need to scan inside the virtual system ? So originally it was a Storage Spaces volume in mirror (2 discs) with REfs system

You shouldn't have created anything after the initial Storage Space (mirror) failed. Instead, you should've disconnected the failed disk and recovered all files from the healthy one.
You can try that right now, but you'll have to scan the healthy disk and see the result.
