Possible False Positive on SMART check in SoftRAID 6.0.5

Active Member Customer

I'm getting a persistent note via SoftRAID 6.0.5 that it sees  SMART errors and potential disk failure on the HD portion of a Fusion drive on a 2017 iMac 5K.  I've run Apple's Disk Utility, Disk Warrior, DriveDX, and TechTool Pro 14.0.2 and not one single one of them finds any SMART errors on that drive.  I'm not sure what to make of the SR warning (not an error but a warning), and I'm not excited about having to replace the internals of an otherwise perfect iMac 5k.  The drive isn't RAID and I'm not sure what/where it is probing when the other utilities find nothing to report.

Advice?  Advise?

There is a bug in SoftRAID where it cannot show the SMART predicted failure parameters of disks in a Fusion configuration.
Do not confuse SMART pass/fail, with predictive failure.

You can be "alive" (SMART pass) and have high blood pressure, high cholesterol, diabetes or any number of issues that an insurance company refuses to issue a life insurance policy (predicted failure), because you are likely to die prematurely.

In the SoftRAID log, I suspect it will show you that the HDD has reallocated sectors.
