I'm on 7.0.1. Was looking at shares on the GUI when it slowed to essentially a halt. In the log I saw lots of messages like this:

It took a few tries to get to the Diagnostics page and then it hung on downloading diagnostics. 

 

So I restarted the server, which now seems OK, but I'm getting the same messages (see timestamps above). I do have a USB add-on card in the server, but there's nothing attached to it. Diagnostics after reboot are attached.

 

Is this something to be worried about?

Do you know what these two devices are?

Hmm... the only Hitachi devices I have are these HGST (Hitachi Global Storage Technologies) drives. But they're connected to SATA ports on the motherboard.

 

 

(If the USB add-on card is an issue, I can remove it. It's not being used for anything.)

Worth a try, and see if those devices no longer show.

And now they're gone!

And so far none of those error messages in the logs.

 

So I'm considering this solved. But in case it's needed for any future issue, I've attached the current diagnostics.
