I have just purchased a 20tb T3 G-raid and would like to use it in RAID 1.
I have followed instructions, using the latest version of the Configurator to configure to RAID 1, but when I try to erase using Disk Utility and format to Mac OS Extended (Journaled), the erase process fails.
Strangely, both Thunderbolt 3 and USB fail, but in different ways. When connected by thunderbolt, I click erase and the harddrive begins the process for around a minute or so, before giving this error message:
When connected through USB, the harddrive has a longer attempt at erasing, around 4 or 5 minutes, but eventually it unmounts and gives this error message:
I’ve tried both quite a few times now, any ideas?
Im using a 2018 MBP, running High Sierra 10.13.6
