It is safer to hold the button down for a few seconds to trigger a proper power down (power button will start blinking). But if that doesn't work, hold the button or unplug the power. A forced power down isn't always safe, but it usually is, and unless you have SSH enabled and the unit will respond via SSH, you really have no choice.

The Duo v1 should do a proper shutdown after you hold in the button for about 5 seconds.
If that doesn't work, then you'll need to pull the plug.
Thanks for the replies. Sorry to take so long to reply myself but a harrowing day yesterday.
I am going to try to shut down and restart. If that does not work, does anyone know if a bad fan would cause a shut down? I would try to replace the fan. It is not running now though the NAS is powered on.
Sequence of events was a proper nightly backup of my computers to the NAS. An hour later a program that verifies the backups failed with path not found. When I woke, the NAS was no longer mapped as a network drive.
I realize it is old and has provided years of service. But I would much rather try to resussitate than buy a new device and take a week to make everything I have now work there such as music and video streaming, computer backups, etc.
Open to any ideas. Fingers now crossed for a restart.
And what I was really asking on the fan recalibrate was does that reset software to read the fan speed more accurately or adjust the fan speed to temperature more accurately? And does it work or better left untouched?

The manual doesn't say, but I believe it is the latter. IMO it does no harm, but I haven't seen much effect on my own system behavior either.
I guess it might be useful when migrating disks to another unit.
The duration of the re-calibration doesn't seem long enough to adjust the effect of fan RPM on temperature, at least to any significant extent. On units with a three-pin fan, then it is likely adjusting the voltage to RPM curve. For 4-pin fans, I don't think it could do much more than check the max and stall speeds, but I'm not sure it even has the recalibrate option for 4-pin fans.
Resync done and all "seems" back to normal. Nothing I could find in the logs as an error when this happened. and I know within an hour of when it did due to scheduled activity on the NAS. So, it dropped off the network and froze to the point the power button would not work.
My only hypothesis is that enough dust bunnies "might" have affected the fan which caused a thermal shutdown. But even so, would not expect the power button to be affected.
So fingers crossed as I start to research a replacement in near future. Two drive for space, great music and video server. Most other wants and needs pretty standard. In case you have a favorite to recommend.
