Synology Ds918+
Unfortunately, the CPU of my NAS 415+ is now also defective. I won't even talk about the warranty :-( Now I want to replace it with a 918+. Can I "simply" insert the undamaged HDs in the appropriate order? Is there a risk that they will be overwritten the first time they are inserted? If so, how do I secure the data on the HDs?
