My Mac was backing up fine to an external hard drive until about a month ago. I purchased a new external hard drive and my Mac won't recognize it. How do I get this fixed so I can continue having my Mac backup to the External Hard drive.
iMac 21.5", macOS 10.13
What Format is the new drive, it should be HFS+ Journaled.
