Before upgrading to El Capitan I made sure my computer was fully backed up onto my Drobo S. The upgrade went fine. I switched computer, backups etc off a week later as I was going away for a few days.
Now back and Drobo S won’t power on. I have done the obvious i.e. check green light on power supply, plugged and unplugged the Drobo, changed power supply socket and it is still not working.
Any idea what I can try next?
Many thanks in advance
