I currently have a shared NTFS partition that may have lost ~49GB of data. This partition is used by both Windows 10 (1903) and Ubuntu 16.04.

The data loss occurred after upgrading Nautilus to 3.18, and it’s worth noting that both Windows hibernation and Fast Startup were turned off.

Windows File Explorer shows that 337GB of space is being used, but the actual content size is only 288GB, and some files/directories are missing.

Are there any options for rebuilding or recovering the filesystem? I have already tried SFC, DISM.exe /Online /Cleanup-image /Restorehealth, sfc /scannow, CHKDSK, and chkdsk /f.

What is the solution?
