SOLVED: G-Speed Studio not seen in Big Sur

I have a G-Speed Studio on a iMac 2020 (prev. 2017).
On the iMac 2020 i have Big Sur Dev Beta 8.
The G-Speed Studio Drive is not recognized.
I have a Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter.

Should it work on Big Sur?
I installed G-Speed Studio Software Utility and G-Technology Assistant.

Solved! :slight_smile:

" Turns out, the kernel extension/driver for the Promise RAID array wasn’t loading. Once I manually loaded it, things worked out.

In a terminal window:

sudo kextload -b com.promise.driver.stex

The array was slow as snot when it first mounted … probably the new beta wanting to index everything on those large HDDs, but it mounts and everything is accessible."
