Hello,

I did Windows 11 22H2 Update. 4TB disk displayed as unallocated space. I assigned letters without formatting, but now I have photos in the disc in RAW format.
What recovery do I need to do? I ran it in a linux environment, I couldn't mount it, I got an error. what should i do i need your valuable help. my operating system is not on this disk.


1.How should I try recoveries without risk?

2. What should I use free/paid as a disk cloning tool? I cannot do disk cloning because there is not enough space.
