Last night I added a 2nd drive to my DNS-320L. Everything looked good. Formatted and mounted. Started copy ~500GB of files to in and went to sleep. This morning I found the copy had failed part of the way. After I couldn't open the mountpoint, I checked and saw there wasn't any power to the DNS-320L.
After powering up and logging in, I see it says the internal temperature reached 135-degrees and it shut down. No the unit isn't blocked in any way that restricts airflow.
So, what should I do?
As I was typing this, I just noticed the fan isn't moving. Is it supposed to always spin or just on demand?
