Given that apparently my fusion 3TB apparently doesn't work well with APFS I thought I'd try one of my external seagate drives, the one with the changeable adapter. Either connected by lightning or usb 3 I get "the operation couldn't be completed (com.apple.StorageKit error 118.) Operation failed...

Any ideas? Repairing didn't work, drive has data on it and is formatted with Mac OS Extended (Journaled). I do have Tuxuera NTFS for Mac installed also.

Thanks

Wanted to add another comment seconding that jonatan.liljestrand comment was the solution I needed. In disk utility > view > show all devices, and then make sure you re-format the disk itself.

Thank you.
