I just received a brand new Nucleus+ a couple of days ago to replace my old Nucleus+ that would no longer start up. My old Nucleus+ had an 8TB Samsung SSD in it with my music on it. I transfered this SSD to my new Nucleus. I tried restoring my database from backup but that failed, and so I ended up just recreating all the metadata from scratch.
Each of the last two days when I went to use Roon I could not play music and received an error message to the effect of “data not found”. When I went to look at the Nucleus+ file system I was able to connect to the Data/Storage folder from my Windows 11 machine, but the folder was empty. Each time I reinstalled the Nucleus+ OS and rebooted the Nucleus+ and the InternalStorage folder then showed up again and I was able to play music. But obviously I don’t want to have to to this every day. I did check the cabling to the SSD and it seems to be solidly connected.
Thank you for the report and we’re sorry to hear you’ve experiencing issues with this Nucleus+.
The team has pulled and investigated diagnostics available from your Core and there’s an indication that the SSD might not be healthy - if possible, we’ll want to try to run a file checker on this SSD by connecting it to another computer.
Additionally, there are network dropouts that are slowing performance on this Core. Do you have an active firewall somewhere perhaps lacking a Roon exception, or filtering settings that might be engaged on a router or switch?
We’re here to answer any questions. Thank you for your patience.
Yes, I can confirm that the SSD was not working properly. On the other hand, I am surprised to see network dropouts. The network is pretty simple, and the Nucleus+ was connected directly into my core switch, which is connected to the router (and is the only device connected to the router). Can you possibly provide more details about the network dropouts you are seeing?
There are client connection failures with RAATServer affecting a Windows 11 Remote dubbed Vengeance. There are similar timeouts on test pings to your Meridian DAC dubbed Ultra DAC.
None of these errors appear fatal - the only unnatural stream stoppage in logs occurs when the Nucleus+ encounters an unexpected I/O failure when attempting to load a track stored locally on Nucleus+ internal storage, corroborating SSD failure.
Roon compensates for most natural network traffic loss in structurally-sound WiFi networks. If you’re not encountering any network-specific performance decline, let’s assume it’s a non-issue next to the SSD problem.
The QA team would like to take a closer look at your database. When you have a chance, please * navigate to your Roon Database Location, compress the Database into a Zip file, and upload it at this link:
