This single partition on the disk has storage files shared between Windows and Mac.
It became inaccessible after a Windows performed a repair reboot on the main hard drive.
Here's what TestDisk has found:
1) Disk selection (Note: disk0 and rdisk0 have the same size!)

2) EFI GPT detected on Disk0. Is this okay for an exFat partition?

3) MS DATA found! The sector size reflects the 4 TB storage. Is this a green light?
