yesterday 1 drive of my mirror Group in Storage Spaces in windows 10 was damaged. So I disconnected both drives , the damaged one and the good one. After that I deleted the complete pool in the Storage Spaces. But now when I connect again the good working drive , it mentions in disc management 'non allocated space'. The RAID 1 mirror in Storage Spaces has the ReFS filesystem and 1 partition (only one drive letter originaly). what are the steps I need to do in Testdisk to get back the data on the good working drive ? So I want to have the good working drive again normally. So to resume :

- yesterday I disconnected both drives of a mirror in Storage Spaces in Windows 10, because of a damaged drive.

- after that I deleted the group in the Storage Spaces.

- than I connected again the good working drive of the mirror.

- but now I see in disc management : "non allocated space" for the good working drive. I cannot see a drive letter.

There is important data (old photos) on the good working drive, so it's important for me to have him working again. For safety I disconnected both drives for the moment until I find a solution for this.

As you can read on

https://www.cgsecurity.org/

there is no support for Microsoft Storages Spaces in the TestDisk package.

Hint:
If you don't generate backups, only use file systems where recovery software exists for.
Microsoft Storage Spaces is a proprietary product which makes programming recovery software extremely difficult as this software would need to be reverse-engineered.

You can try out PhotoRec at least. This won't bring back files and folder structures but maybe it finds something.
If you want more search for commercial solutions and/or data recovery labs.
