Yes, that’s about what I expected, thanks.
So I understand that there’s a certain need to make those checks but a solution to fix only if quite sophisticated backup measures are taken.
All this seems to be a practical matter at max. for IT nerds like us but not for the average streaming customer, so I think the recommendation of flac for this reason is in fact also quite limited to this target group.
But at least it’s interesting to know if/how much of a library is slightly corrupted. For my part, I’ll probably ignore it and in case of an occasional nameable audible problem I trust in the options to re-acquire the stuff. I fear, different than your experience, if something’s corrupt it would be so on all of the backups in most cases.
