Drive Bay not recognizing drives

I have a Drobo which is about two months old. I just went to add a couple of old SATA drives from my old PC and find that Bay 3 (from the top) is not recognising either drive.

Both drives are recognised just fine in slot 4. Is there some way of telling if the bay is faulty before raising a warranty claim?


Reboot your drobo with the drive in.

Thanks for the quick response Jennifer, that worked a treat.
