Background: I got a new computer recently, a new MacBook Pro running High Sierra. My old computer was a 2011 MacBook Pro, and I used an external drive to back it up with Time Machine. The drive has two partitions, both Mac X Extended (Journaled), and one contains my backups (Mac Daddy) while the other is empty (007). I no longer need two partitions on the drive, and would like to merge them without losing my backups.
Problem: Disk Utility is being less than helpful, as you can see it won't give me an option to do any partitioning on them, and in fact it doesn't even recognize the two partitions as part of the same drive in the sidebar, though under "Device" info it does say they are both "disk2". I've already erased 007 and run First Aid on both just in case, but nothing changed. I imagine I may have to use Terminal, but I don't know how. Any help would be appreciated!
P.S. I know this is similar to other questions, especially this one which never got solved, but I figured I'd redo it with my specific info.
