I have a Drobo (regular... no 'S') and I just bought a new iMac 27" with a Firewire 800 port.
I can connect my Drobo to the iMac via USB 2.0 just fine works as intended. However, when I attempt to connect the Drobo via Firewire the Drobo is either non responsive or doesnt mount at all. Selecting it in the Finder just makes it beachball.
Is there anything I just check?
When I go to System Profiler > Hardware > Firewire I get the following message:
Warning: Unable to list FireWire devices. Maximum Speed: Up to 800 Mb/sec
I have Drobo Dashboard installed and it detects the Drobo initially then when I attempt to browse the drive Drobo Dashboard says its not detected.
