hi airbogo,
am not sure if your power supply is working 100% but you might be able to check this by looking at this page to see if the lights are ok:

also, it might be worth trying to put your drobo into a readonly mode, for example as mentioned here, as it might be able to let you access your data again to copy somewhere:

if those do not work it might be best to raise a ticket with the support team (and i think you could still raise a paid ticket if you wished) but please let us know how things go.
