Windows update error ... (Patreon)

A few moments ago I finished making the new video and received a Windows 10 update, I thought everything was fine until I found no hard drives where I have saved my work ....

Apparently windows formatted two disks used only to save files and where I have the operating system I only update without deleting anything.

I hope I can recover the files, I have almost two tb full of files, and I do not know if I will be able to recover them all but I hope that at least the most important thing to continue working to recover my files is there Q_Q
