I've used the softraid 6 GUI application to create a non-Raid HFS journaled Volume which I am using for TIme Machine. Can this volume be read by a Mac without a SoftRaid Licence?
For whatever reason once Softraid 6 utility had touched the Hard Drive when I used the Apple supplied Disk Utility application the machine would hang whenever I tried to erase the disk to create a regular partition.
On Intel, yes, as we bundle a limited version of the driver with all macOS released. M1 systems do not have a functional SoftRAID driver bundled. So to mount on an M1, you need to install a SoftRAID driver.
If you want to work with a SoftRAID formatted disk in Disk Uiltiiy, use "Zero disk" first, to erase the partition map, as Disk Utility has a bug where it hangs if it encounters a SoftRAID formatted disk.
