Why shouldn't you drag and drop to copy a Library from one HDD to another?
I cannot recollect whether I have or have not moved a Library in the past but I have seen lots of answers detailing comparatively complex procedures including this video.

What is the problem with simply dragging and dropping?
I have just tested the drag and drop method and as far as I can see everything is perfectly normal.
I must admit that it was not a complex Library so maybe that has some bearing on the issue?
