I am planning to build my first machine. One thing I have not had to face before is the question of file integrity etc when placing the data on another disk than the OS one. Also how to make this work smoothly. As on a "normal" installation I like to keep data for different users separated to maintain privacy and reduce risk for accidental damage on other users files and structures. I also like to make it easy to save data from various programs without having to climb "trees" when saving on the right disk.
How would a smooth and safe setup look?
