“Help me!! One important volume is missing from my Mac Pro machine from yesterday. Unfortunately, it happened just after upgrading the OS to macOS Sierra. But, I don’t exactly know whether I should blame this OS or not, because this volume was created prior to this upgrade using Disk Utility and I had moved some of my very important data to it. And, frankly saying, I wasn’t really concerned about that data. Now, I’m paying for it.
If any of you can tell how to recover that lost volume, it’ll be greatly appreciated. I don’t want to roll back from Sierra to my older version ( El Capitan)”.
