da0 is the boot drive. However, looking at the boot volume shows "Condition:HEALTHY":

and:

What's going on here? The general system health alert "traffic light" at the top right is green as well.

Thanks!

EDIT: I've made NO configuration changes to the system (hardware or software) for the last year+, and these messages were not there before. I can't say when they started appearing - it could, possibly, have coincided with the U4 update i did a few days ago. but I'm not sure.

OK, this is weird. After a reboot, the messages stopped. I guess I'll just chalk it up to the elusive software gremlin, but I'll remain diligent and await it's return.

Ok, the messages are back again. Seemingly no other issues. Any suggestions, please?
