Just had a moment of total horror. Having a bad problem with the Drobo5N which is bad enough that I think it needs an RMA.
Saw advice which said that if your drives are all showing as green/good and your Drobo wont mount them, it is likely to be an OS corruption error. The symptoms are the same. Thinking myself all safely backed up I went through the process suggested. Taking out all of the drives, manually updating the firmware. Then putting them all back in.
Again drives are in but the Drobo is now not responding at all to the dashboard or anything else.
Was just putting the data on another NAS device after which I realized that around 70% of 5 years of personal photos and videos of my children have not been backed up although everything else had.
So, as the drives dont seem to be damaged. When I get the RMA unit and plug them in will I be ok? Assuming the drives really are fine (and I really think they are) will they just slot in a new unit and allow me to recover all the data?
