Is there anything I can do to rebuild the partition table back to a healthy APFS Volume state? dev/disk5 (synthesized):Ġ: APFS Container Scheme - +499.9 GB disk5Ģ: APFS Volume HD - Data 231.6 GB disk5s2īefore the partition data was damaged, it has a Container and two disks HD and HD - Data.

UPDATE: here is the same data from the 500GB HD that was cloned onto the 1TB drive - if seeing how it used to be is any help. Turns out testDisk doesn't recognise APFS Containers and it has written it back incorrectly. I didn't make any changes intentionally to the disk layout, but since then it is messed up. I regretfully deployed testDisk - intending to look, but ended up saving the partition table.

I have booted of an SD card and I could see the drive and browse it as read only. This week it decided to stop booting - was just hanging on the loading screen.
