Pointing my catalog to my backup RAW files

Hello all,

I've had my Lightroom images and catalog files on on external drive, and today mid-edit, the external drive corrupted. It has become read-only and basically made my catalog unuseable. Luckily, all my RAW photos are backed up on another drive. Also luckily, I've been able to copy the .LRCAT file from the old now-read-only external drive, to the new hard drive as well.

Now, when I open the copied .LRCAT file, Lightroom opens just fine and shows my edits all the way up until the external drive locked itself down. However, that LRCAT file is still looking at all the files on the now unuseable read-only drive. How do I tell my catalog that I'd like it to keep all my edits, but reference the exact same RAW files that I had backed up to a different external drive?

I'm not sure this makes sense. But it comes down to the idea that I need to tell my Ligthrooom that I've basically moved my RAW files to a new location. Can anyone give me a hand?
