JimmXinu - I did some searches, here's some posts I found about what Replace Device does:

Specifically, I've never been totally clear on the two "Replace" options for syncing. How is the "Replace device with list, add new items only" option different from the "Add new Items only"? And how is the "Replace device with list, add/overwrite all" option different from "Replace..., add new items only"?

"Add new items only" doesn't update books on the list that are already on the device.
"Add/overwrite all" copies all books on the list to the device, copying over those already on the device.

Just one further clarification on the "Replace device with list..." options. The books that get removed from the device must also exist in calibre (just not on your reading list). So for instance if you have dictionaries or other books on your device that you have not put in calibre these will remain untouched, regardless of what you put on your reading list.
