I have a G-Speed Q USB 3, with 4x4TB drives. It was configured as Raid5, I just upgraded to a G-Speed Shuttle 24TB and copied off all of my data. I have a Macbook Pro with 10.13.3. I thought it would be still useful to reformat it, since it has been years and use it as a 2nd backup or sell/give away. I attempted to load the Configurator but it quits, I attempted to use the Apple Disk Utility and after two days of initializing the drive it failed. So now I have an unmountable 16TB paperweight.
You seriously don’t have any updated software that can reformat/reconfigure this thing?
