I am trying to switch to a new external hard drive. I solely use an EHD, with backups, to store my current photos. I'd like to use a new EHD for this year's files as well as copy some old ones there as another backup (my current EHD seems finicky). What is the correct route to doing this? It seems that if I "add" the new EHD under folders, it makes me import all of the photos like they are new. I don't want to import because I want to preserve the edit history of the files. What am I missing here? This seemed very simple and after several attempts I'm still not getting it. Thanks in advance.
