Lightroom 2 Mac has wrong location for Files. How can I correct?

I was away for the summer, and moved my files to an external firewire drive. I would start Lightroom by double-clicking on the catalog. Everything worked fine.

When I returned home, I copied the catalog, previews, and lightroom database back to my computer.

I set the preferences to start up from these copied files. No matter what preview I click on, I am told that the Files are offline or missing.

When I find the files in the Finder, they can't be found, but the message box shows the path, which is to the Firewire drive.

Is there a way of quickly converting the file locations in the catalog to the new location I want?

This is a Lightroom Problem - I didn't think that I needed another zone.  I see your point that if it was in some sort of Adobe Forum it might be seen by an expert who normally wouldn't visit Lightroom but knows the answer.
Try starting Lightroom while holding down the Option key and specify the path to the database.

You might also see if you have a permissions problem. Are you using the same User you did before the summer? You might check ownership of the current files and make sure that they match your user. Then use a utility other than Apple's to repair permissions (and ACL's) such as Cocktail.app.

Holding down the option key while starting Lightroom 2 only gives the option of selecting the catalog, not the photos.

It's not a permissions problem. The catalog is pointing to the external drive, not the internal drive.  This indicates to me that the catalog has the path for the external drive saved with all the files.

I was wondering if there was a way of changing all the paths in the catalog file with one command.

I lucked out and solved this problem in a way I didn't think possible.

I started Lightroom. The alert came up asking if I wanted to backup the catalog. I agreed to do so.

As part of the backup process, Lightroom performed a diagnostics and repair.  It took a while, and at the end all the photo paths were somehow corrected.

Whew!

Thanks to all.

I was able to have Lightroom's built in utility repair the problem. I still don't know for sure what caused it.
