Hello everyone,
I asked this question in the Terramaster community but unfortunately never received an answer.
I think this issue may also apply to other DAS manufacturers.
So, here’s my setup:
- Terramaster D4-320
- WD Purple HDD (WD43PURZ)
- Beelink Mini S12 Pro running Proxmox 8.4.x
When I shut down the computer, the DAS continues running. To turn it off, I have to press and hold the power button for about 3 seconds, as stated in the official documentation.
Now, about SMART:
After every DAS shutdown, the Power-Off_Retract_Count parameter increases.
Some sources say this indicates an emergency disk shutdown, while others consider it normal for the counter to increment.
Can someone finally clarify—is this bad? If so, why would the manufacturer knowingly release a DAS that behaves this way?
Before buying, I read many reviews about the Terramaster D4-320, and no one mentioned this behavior (Power-Off_Retract_Count).
I’d really appreciate an answer.
