Creating a new catalog questions

My suggestion would be to plug in both HDDs and store your photo files themselves there.

I keep my LRc Catalog on my internal SSD on my mac, and when I quit LRc, I have it make a back up of the catalog and place the back up on my external HDD. Occasionally, I go thorugh and delete some older backup catalogs if all is working well.If all my HDD's are connected to my Main Mac, when I launch LRc, all the photo files are available to me and they appear under the DRIVE section and then in the FOlders of that drive depending how I organized them.

Just remember to use Lightroom as a main hub to move as well as edit your photos on disk.

Is it best to create a new catalog on the new HDD and then add the new HDD to the 'folders' section of LR?

I would strongly advise against creating catalog for a new year. I consider this to be a very poor practice. One catalog can handle files on mulitple HDs. But multiple catalogs fragment your control over your picture collection and introduce multiple disadvantages, compared to having one catalog. So keep your life simple, use one catalog.

I would like both HDDs to be connect and visable in LR at the sametime.

It sounds like you might be thinking about creating a new separate catalog just for the other hard drive. Be aware that if each drive has its own catalog, you won't be able to achieve the goal in the first quoted sentence because Lightroom Classic can open only one catalog at a time.

To be able to have all photos on both hard drives available in Lightroom Classic at the same time, use just one catalog. For example you can keep using your current catalog, and just have it add the contents of the new hard drive.

That works because Lightroom Classic lists each cataloged volume separately at the top level of the Folders panel. One catalog can track files across multiple hard drives.

Funny - I have almost exactly what Jim Hess has... and it works well for me. SO maybe that IS the way to go!

You can either put the catalog on the new external hard drive, or you can keep all the catalogs on the internal hard drive and put the images on the external hard drive. The choice is yours. I have multiple external hard drives, and have one of those external drives dedicated primarily to storing the backups of my catalogs. It doesn't store any working folders of images. But that is just my choice of how I use the hard drives.
