Head's up for anyone who uses DriveDx. The latest 1.11.0 update breaks all USB SMART monitoring on Big Sur 11.4 (20F71). Reinstalling the driver does not resolve. Physically disconnecting and reconnecting after cold boot does not resolve. Drives were reporting prior to the update only when connected after boot. Now getting "Diagnostics of external drives is unavailable" message for every single USB drive.
This has become more and more of a problem with every macOS update in Big Sur and seems to be getting worse. Monitoring for the internal Apple issued drives and true Thunderbolt connected are the only that report successfully.
