ATA Errors Not In System Log

Well, according to the smart_history.log:

I don't know what others might think, but I think 3000+ or 9000+ uncorrectable errors is probably a fair bet for having listed in the regular log display as "significant". ;) This was actually a drive that was previously in use in the 516 and later replaced with an 8TB disk in a newer deployment. But it certainly wasn't experiencing this sort of failure rate until very recently. Clearly, it is in bad shape and requires retirement.

What strikes me as odd is that I'd see all kinds of pop-up displays in the web UI /while/ these errors were building, and perhaps even get email notifications for them, but they don't apepar in the "Logs" display in the web UI? That's the head scratcher. Maybe there's a reason for it, but it seems like it'd be making difficult to see something really should be visible... if for no other reason than to allow someone to log in and see what's been going on at a glance if they get email notifications, and to corroborate the events without needing to download the logs .zip file.
