Gentlemen, we’re missing a more important point here, since Roon had introduced measures to prevent backup of corrupted databases in build 882, see except:
Starting in Build 880, Roon now validates the entire database before performing a backup, which helps prevent Roon from backing up a corrupt database. This will ensure that the databases that are backed up will be valid for restore (assuming the media they reside on is not failing).
This change mostly affects behavior around the backup process, but also makes Roon more vigilant about detecting corruption during normal use of the product.
My disk still checks out 100% healthy, yet there‘s latent corruption rearing its ugly head in a seemingly random pattern, can be back-uped and restored without Roon stumbling over it.
Looking at the evidence, I have a hard time believing my hardware is failing.
I think Roon needs to investigate further to find out what exactly is happening.
