I was creating a bootable Mojave usb for a friend on my Mac and by mistake instead of formatting the USB drive I formatted an NTFS partition on an internal disk to macOS Extended (Journaled). The format did not complete though and ended with an error but the damage was done and the partition is just greyed out in the Disk Utility and is not visible in the Finder. The disk in question is a GPT 1TB drive which has a Windows 10 partition of ~225GB, one that Windows makes itself during installation, while the rest was the data partition which got wiped. I haven't touched the partition in any way except running testdisk analysis on the drive.
This is the output from the testdisk analysis
The selected partition is the Windows 10 partition I think. I cannot find the ~700-750GB partition in this list. I don't have linux installed on this system although I had 2 images of backed up Ubuntu on this partition.
Can you guys please help me in figuring out what the safest way to recover this partition is?
