! URGENT ! How to check RAID working properly?

Mac 10.13.6 G-RAID TB3 8TB removable

I need to find how to check that the RAID 1 status is working correctly, plus info on the safe procedure to remove and swap drives … can’t seem to find this anywhere!!

I just responded to your other post about it. The fact that the drive shows as half the capacity means everything is working fine.

RAID1 is not designed for swapping drives. It is not under protection if you remove a drive. The whole point is to keep them together so you have duplicate copies.
