Though I would ask for any ideas as this just seems very odd. I bought two Drobo S units at the same time (feb 2010), had them each plugged into there own firewire port on a 2009 Mac Pro. Rebooted the Mac Pro and now both of the Drobo S will not boot up, they just keep rebooting and rebooting. I checked the support site and followed there instruction but nothing seems to make a difference.
Has anyone any ideas as to why both of them would do this? They were bought at the same time and i have never had problems with them before this.
Thanks for any ideas or suggestions
