My Classic Mac Pro 5,1, which is a flashed 4,1 has been upgrading and running the OS without problem up to 10.13.6. Disk Utility just indicated a consistency error on the boot drive, which is a 240GB APFS SSD with 100GB free. When I tried to reboot from the recovery partition it just booted from the startup. Looking at the drive in disk utility I see there is no recovery partition. The boot disk has 100GB free with 4.8 purgeable. How do I add a recovery partition? Is it possible to add one to a free 127GB scratch SSD?

Carbon Copy Cloner by Bombich may do this for you, I know it can create a recovery disk but I'm not sure if that requires an existing one.
You can experiment with the free trial.

You might try this utility:

You can also make your own recovery USB drive:

As has been posted... Carbon Copy Cloner can create a Recovery partition for you and no, it does not have to have an existing one available to do so. CCC has a fully function trial version you can download from their site.

Great and thanks. According to Disk Utility the inconsistency can't be repaired. I will have to clone the disk to a new drive, per Drive Genius, and reformat before cloning back.

Thanks for suggestion. Will definitely try it. My Boot drive was APFS formatted. When I clone I think I will go with the old HFS format so I can use Disk Warrior.
