Redirecting Lightroom paths

[Eridium]

Forgive me if this is too easy a question for you veterans:

I want to change Lightroom paths ...
I used to have all of my photos on an external 1TB drive.
That drive is dying so I bought a 2TB internal and would instead like to move Lightroom's main path:

From: my old G-Drive/Photos
To: Macintosh HD/Photos

Using Lightroom 2.6

When I start Lightroom now all of the files are Red/shaded out.  I'd like Lightroom to change the photos' root folder to MacintoshHD/Photos and have all of the subfolders remain intact in their original structure.

Thank you.

Right click folders and choose Update Folder Location.

Another right click option is Add Parent Folder - this may help you reduce the relocating work.

In future, use Lightroom to move files.

Thanks John, that worked.

In future, use Lightroom to move files

In this case it wasn't possible.  The external HD I was using would not mount correctly, usually crashing finder, and Lightroom would crash all the time.  Moving 30 GB of photos within crashing Lightroom wouldn't work, but when the HD mounted for long enough, I could transfer over files, rescuinged by copying onto another drive using finder/Mac OS.  Now everything's up and running.  

Now wondering if I should upgrade to LR3 or not....
