I have been using Drobo drives for years with WD Reds and have randomly suffered from the Dashboard reporting disks as Failed with the red light flashing. This only happens after I correctly eject the drive, power the Drobo 5D3, 5C or 5N down, and re-start it. Is this normal behavior, please?
To fix the “failed” disk I remove it, erase it and stuff it back in the same Drobo slot, so it thinks it’s a brand new working drive. Within 24 hours all disks are working properly again.
I make it my practice now to never turn my Drobos off as the above procedure is making me frustrated.
Does anybody have any helpful advice, please?
