drive red, then green

Can anyone tell me what is causing this?

  • Drobo alerted me that it was going into “protection mode”
  • on Drobo Dashboard, one drive was red
  • on Drobo Dashboard, all drives were yellow
  • on Drobo Dashboard, a DIFFERENT drive was red

Now, on Drobo Dashboard, all drives are green

What is it doing?
Can I find out which drive is really bad? Is there one?

UPDATE: now it’s repeatedly going into Data Protection mode, while all the drives are green. It’s done this 3 times so far!

Few questions to help us orient ourselves:

  • What Drobo do you have?
  • What drives do you have in it?
  • How is it connected?
