I can’t find any instructions how to set up my new G Raid to RAID 1 for Mac OS 10.13.3 High Sierra. After using the G Raid utility to change from default RAID 0 to RAID 1, it jumped to Mac Disk Utility. I think I’m supposed to erase the drive, which is now showing as 6TB, and it asks how to reformat it. Because it’s High Sierra, should I be erasing and formatting the 6TB as APFS (not Mac OS Extended). Should it be APFS, or APFS Encrypted?
And since only one 6TB G Raid drive is showing, I hope that the erasing and formatting applies to both drives. Is that the case?
I was having a LOT of trouble setting up my new G-Raid 16 TB. When I plugged it in to my MacBook Pro running High Sierra it was fine until I used the G-RAID with Thunderbolt app to switch it from RAID 0 to Raid 1. It then started giving error messages and would not mount even though it showed up in Disk Utility. I was a little nervous about erasing it even though it had no files on it yet. This solution worked! The only difference is my selection said "Mac OS Extended (Journaled).
I was ready to send it back to Amazon.
Thank you for having this solution online here where I could fix my problem!
