I have Big Sur OS with newest upgrade 11.2.2 and Mac Book Pro M1 2020 version. I'm using Thunderbolt 3 Dock Core and connecting external USB hard drives. They are mounted. Can be seen on Finder and there is an icon on pulpit. First aid done. Disc can be seen. Disc utility shows size of files own hard drive but is not showing the files itself. And it is for all external drives. :( On Microsoft Windows it works without any issues. Please help and do not say that I need to format a drive - it's just ****** and this is not a fix. :|
