Drobo won't rebuild, keeps ejecting! Please Help!

One of the bays started blinking red. I had three messages is dashboard: 2 of them said not to remove the bad drive, its rebuilding. The other message said to remove the bad drive and replace it. I went ahead and replaced it. Now it keeps rebooting/ejecting itself. I don’t think its rebuilding. can you guys help me?

I have drobo gen 3. usb attached. mac os. I am super bummed out if I can’t save my data.
