Why is Unraid warning me about a low raw read error rate, but not about a high one?

[qix]

I have a WD Red 2 TB disk that's about 3 years old at this point, and Unraid 6.12.6 is warning me that it has a raw read error rate that is over the threshold.

However, I have a disk that is almost 10 years old at this point, with way more (1546 read errors) that Unraid is NOT warning me about. Is there some other metric that triggers the lower read error rate as a warning? How am I supposed to interpret these different diagnostic results?

That attribute is not monitored by default, maybe you are monitoring for one disk and not the other? Please post the diagnostics.

Here are the diagnostics

smEvents="5|187|197|198|199|1"

 

Both 1 and 199 attributes are being monitored for that disk, and I would suggest doing the same for any other WD disks, since those attributes increasing is never a good sign.

Thank you!
