I have two WD My Book Studio 2 drives. Both set up as RAID1 a long time ago. I want to reset one of them to RAID0. I installed the WD RAID Manager on my computer running Mac OS X Mojave.
After rebooting I see the WD icon in the toolbar. I can click on it and select WD RAID Manager which opens to show the attached drives.
After changing the RAID level, I click confirm and enter admin credentials as required. Then the application just sits there with a multicolored wheel spinning away forever. Nothing changes on the drive and I have to reboot the Mac to get back to the WD RAID Manager.
The same thing happens with both drives. I even tried changing the RAID level via my MacBook but get the same behavior.
These are Firewire / USB drives and I tried the process connecting them via both interfaces. Nothing,
