Gen 2 Data Protection Loop

My Gen-2 Drobo keeps looping through Data Protection. Two of the lower drives blink in red. All four drives are 3 Tbs. This started happening from today. Are my drives bad (unlikely two will fail simultaneously) or the Drobo enclosure is faulty?

While it’s unlikely to have two drives fail at once, it’s not impossible. It is also possible the Gen2 is failing. Hopefully you have another backup of your data somewhere.
