I moved a 10tb drive from an USB enclosure to inside of a PC with a sata wire, and somehow some folders got erased, but the drive data total still shows about the same
It's possible that some of the files are recoverable by checking the drive for errors, but maybe we should hear from the experts on
whether that could cause issues with a better recovery of the files (especially because that would erase their names and date info).
If you decide to try that, here's how: Right-click the drive in File Explorer/My Computer > Properties > Tools tab > top section.
(If you do that and it says errors have been fixed, report that here for help finding the recovered files.)
