See attached screenshot. Should I click 'Copy Original Media' instead of just the Event? I think you are suggesting that if the Media is on an external drive only the links will be copied, but not the actual Media. It's only if it's contained in the original Library itself will the media itself actually be copied over to the New Library. Have I got that right?
Meaning if I click Copy Original Media ... it'll just be linking the clips in the NEW Events, NEW Library, to the Original Media stored on an external drive?
Copy means copy... and in this case you need to. You will see new real files inside the new library - not symlinks to the old one.

FCP is pretty smart about this, and as long as the two libraries are in the same drive, it will avoid duplication of used space; you will see a file for each piece of media, stored inside the respective library, but they are "hard linked", meaning that only one of each exists on disk. This makes sense, because all editing in FCP is nondestructive: FCP never alters the media files themselves.
Copy an event from Library 1 to Library 2 - WITH media (there is only one file in this example, Solidos.mov)
Media is stored INSIDE the library in BOTH cases. Note that BOTH files are 72 MB (a very short movie, but NOT an alias; also there is no curved arrow in the icon)
So each folder has its own file.
However, due to the magic of "hard links", the data is stored only one on disk.
Running ls -l on the Terminal on each folder, you will see this
That number 2 in
"-rw-r--r--@ 2"
indicates that this content is referenced in two places. The magic of the file system ensures that they are preserved. If one of them is deleted, the reference count is decreased, but the data remains. Only when the last reference goes away is the data on disk actually freed.
