I have a Mac Mini with Big Sur. My Drobo 5D is connected by a Thunderbolt cable with a genuine Apple Thunderbolt 1 to Thunderbolt 3 adaptor.
Like everyone else I lost access to my Drobo with the Big Sur upgrade.
I have now updated to 3.5.2. The Dashboard recognises the Drobo but Finder will not. It’s not available when I Go To Volumes
Under Disk Utility it shows as uninitialised with no option to Mount.
Dashboard reports it has the latest versions of Firmware and Dashboard
Now when I boot with the Drobo plugged in via the Thunderbolt cable, the startup hangs midway, shuts down and try’s again to restart. This is a death cycle!
NONE of these things happen when I connect via USB and everything is normal except the speed
It would seem 3.5.2 still has not resolved the issue…unless anyone has ideas for me? USB is so slow
