I am about to go nuts with this. I have a 1 TB hard drive in my computer that is named "Lightroom." It has the files I have imported to LR (2010, 2011, and 2012), the catalog, and a few other items and it is now full. I would like to replace it with a 1.5 TB hard drive (say named "Lightroom 2", which would have my 2012 imported files, the catalog, and other files I will import in the future. I don't want the 2010 and 2011 imported files to reside on the new hard drive "Lightroom 2." I would like to remove the hard drive "Lightroom" from the computer and use it as an off-line backup of the earlier files. I have discovered that just copying the files and catalog to the new drives is a big mistake. Nothing I have tried works. I would greatly appreciate any help anybody can give me. To repeat, I want to replace the hard drive I am currently using in my computer with a slightly bigger one, and use the current one as a backup. I would prefer not to see all the folders etc on the replacement hard drive appear with a "?" after their names (don't want to see them at all until I reconnect the original hard drive back to the computer.
I suspect that I could keep the current drive in the computer and "move" the files I want to archive to an external drive. As I understand it, this would free up space on the internal drive to add more files. Am I correct about this? However, I really would like to have the larger hard drive in the computer.
I have been using 2 drives in the computer, "Lightroom" and "Lightroom bk". As I import to the first drive I have it backed up to the second drive. Both internal drives are now full. My reason for doing it this way was that I could then replace both drives and use them as archives. Maybe this is not the best strategy. I am certainly open to a new strategy if that would be better.
Thanks in advance for any help anybody can give me.
