I am in the process of Tagged about 30,000 photos using LR3. All of the photos were saved in seperateseparate folders under "My Photos" in Windows 7. Now, since my C drive is nearly full, I am installing a new drive in my PC. I plan to copy all the photos from the C drive to the new drive to save space. Once I transfer the photos from the C to the D, I believe I will need to import them into light room 3 again. This is not a problem, but the question is, will I lose all my tags and have th re-tag them again? It has taken me 4 days to properly tag the photos and I'd hate to have to do it all over again?
