· ref#BOHWVD not resolved. I tried to follow your advice to back up the storage onto an external hard drive. I connected a Seagat hard drive to the Nucleus USB port and was initially able to see the hard drive on the Nucleus folder on my Mac. I had diconnect the hard drive and when I reconnected to the nucleus, although the hard drive was powered on I was unable to see the hard drive on the Nucleus folder on my Mac. Very odd. I tried to reboot, restart the nucleus and to no avail. The Nucleus quickly reads an alternative USB stick (only 256GB) and the hard drive is capable of being read when connected direct to my Mac. I want to avoid spending $80 to buy a new hard drive. Can you pls troubleshoot this issue?
What format is the HDD it should be exFAT otherwise you need to dismount “properly” a la windows
Try plugging it into a Windows PC and Repair the drive ,(Not sure how to do that in Mac) if that works you should consider reformatting exFAT (COPY the contents first) if you intend to remove it. NTFS works but only if you leave it alone.
I have had a USB NTFS in myNUC for 3 yrs now BUT never removed !!
It sounds like we have a mix of the original database issue and a new USB drive mounting issue. Let’s untangle this to get you back up and running without buying a new drive.
1. The “Loading” Issue (The Main Problem) First, we need to know your current status:
Did you successfully rename the RoonServer folder to RoonServer_old and restart the Nucleus?
If No: You must do this step. Without it, Roon will remain stuck on the loading icon indefinitely because the database is corrupted.
If Yes: Are you now able to open Roon and see the “Login” or “Setup” screen?
2. The reason the Nucleus won’t read the drive now is likely because it was unplugged without being “Ejected” in the Web Interface first. Linux (the OS on Nucleus) is very strict about this and will refuse to mount a “dirty” drive.
Plug the drive into your Mac, open Disk Utility, and run First Aid to repair the filesystem. Once repaired, the Nucleus should see it again.
3. Since you mentioned you can see the Nucleus folders on your Mac (via Network/Finder), you don’t actually need to physically plug the USB drive into the Nucleus to perform a restore.
You can drag your backup folder from your Mac (or the drive connected to your Mac) and drop it into the Data > Storage > InternalStorage folder on the Nucleus via the network.
When you launch Roon, select “Restore a Backup” > “Browse…” and navigate to that internal folder.
Important Note: Only use this method for this one-time restore. We strongly recommend keeping future backups on an external drive or network share, not on the Nucleus internal storage.
Please let us know if you are still stuck on step 1!
· The copying process from my Nucleus to my external hard drive was interrupted more than once. I will try again next week and come back here if I have any updates.
How are you doing this? If you are using a pc to copy music from the internal drive of a Nucleus to usb drive connected to the Nucleus: then you are copying the files to the pc and then back down to the nucleus. A lot if network activity especially if there is wifi involved.
A better way is to put the external.drive on the pc and copy from the nucleus tonthe drive attached to the pc. The data is only making one trip.
If this is not what you are doing, then please ignore my post.
Certainly keep us in the loop on your progress. If you experience any issues, please take down the specific date and time of the issue, and we’ll enable diagnostics to take a closer look.
