G-Raid T3 8TB Configurator No Device Found RAID 1

gilclo See the solution above. If that works, you need to initialize on prompt. If you happen to miss/skip that step, you can go into disk utility and then erase that drive; here’s the link to where Rydia explains that step: G raid 8T New, just configured Raid1 "Not recognized" on MacBook pro - #8 by Rydia

Hope that helps.
