I have an Imac (2017 model) running Catalina with a G-Raid 12TB running in RAID 1 connecting via Thunderbolt.
The computer and drive are powered off at night because the electricity where I am is not stable.
If the drive is connected to the computer when I start it in the morning, the Imac screen comes up blank. I have to use the button to power off the computer and restart after pulling out the Thunderbolt cable.
So I end up pulling the cable out every morning, starting the computer and then connecting the drive and starting it up.
Does anyone know why this is happening? Constantly pulling and reattaching the cable is probably not good…
