Hello Folks I am still quite new to LR so I am still on the steep part of the learning curve. Maybe someone can help me out here. I recently erased my my hard disk drive and have since re-installed Lightroom 2 (I know...I'm behind the times...). I am currently trying to restore my photos. What I have done so far was to copy the entire "Pictures" folder (OSX 10.6.8) from my backup drive to the newly formatted hard drive in the "exact" same location. So the Lightroom catalogs and the Photos themselves are located in the "exact" same locations as before. Notice the quotation marks It is almost the same location because when I re-installed OSX, I gave the home directory a different name because I was not thinking straight. So I am thinking that the catalogs are having trouble associating the previews, "Develop" settings, and additional metadata with the original photos. These are the symptoms: When I open LR, I see my preview thumbnails as I did before (i.e. as expected). However, when I go to operate on the photos (i.e. zoom in on one, etc...) I get the message: the file named "_.dng" is offline or missing. I am guessing that the catalog is pointing to something like: Code: users/OLD_username/Pictures/LR/_.dng where in reality this data is located at Code: users/NEW_username/Pictures/LR/_.dng Any thoughts on this? If I can't fix it, no big deal, but it would of course be much more convenient if I can. Thanks!
