New RAID 5 Volume says "unable to create file system" and won't mount
Here you go.
I chatted with OWC tech support and they suggested disabling my T2 chip, of which this machine has none.
I also noticed after I uninstalled and reinstalled SoftRAID that I got a popup saying the installation of the driver failed. But then when I restart the application it says driver v5.8.4 in the corner.
