@Alucardx23: Of course the model (Synology box) isn’t on the list, it isn’t a WD product. But how does it “not being on the list” make it a problem or not?
@detonation: Improper shutdowns are called improper for a reason. Something, some procedure, isn’t being done correctly. That isn’t a good thing. Improper shutdowns can cause file corruption and sometimes bad sectors.
But for us to answer your question in the detail you are expecting… We don’t have enough information to do so. I have no clue as to what the shop is doing with your NAS box. And therefore cannot speculate on what damage is being caused, if any. Maybe these improper shutdowns are part of what they do to test them? Who’s to say?
When you get your box back I would suggest you run the extended non-destructive read test on each disk. It’s the only way to gain some confidence that there are no bad sectors due to improper power-downs. And check the SMART values while you’re at it.
