I have spent much of the afternoon today trying to define the issues and set out what I have to do to make this right. Unfortunately, I don’t have a recent backup - the last one was about a year ago, and I have a lot of new music. So, the easy way forward is not available.
There seem to be two issues. One I can deal with (re-combining multi-disc sets), and one I need advice on. What is happening indicates database corruption: multiple copies of albums were created, or are being created, and if I delete the duplicate copy, the actual underlying music files are deleted from the hard disc (not just the redundant database entry) and all copies of the album disappear from Roon. If I re-copy the album from the NAS back to the Sonictransport and re-scan, two copies of the same thing show up, not just one. What’s worse, in the case of multi-disc sets the different (disaggregated) discs can have different artwork.
I have kept a copy of all ripped or downloaded tracks I have copied to the Sonictransport separately on my NAS. Is there a way to delete the ripped or downloaded music from the Sonictransport and the database without disturbing the Tidal and Qobuz links? I don’t want to lose these. (My library is about half ripped/downloaded and half linked). This issue with duplicates doesn’t exist with linked files - it’s only with regards to music I have ripped or downloaded and installed on the Sonictransport.
The new Help system is a definite improvement over what existed before, but it doesn’t go this deeply (at least I haven’t found a recipe for what I think I need to do). Any suggestions would be appreciated. Thanks!
