S.M.A.R.T. Error MacOS 11 Big Sur Beta Installer
I would load the app DriveDX which specifically looks for the SMART status of the drives. The app is not free but has a free trial period. You can use that to check your drive. It will tell you the SMART status and details about the drive. It very simple to use. Just start the app and it will start scanning your drives. Give it a minute or so to complete and display the results. See the image below for an example of the output. Yes my drives are failing or have failed.
