To check the S.M.A.R.T status of the drives in your Genesis ZX you will have to gather the support logs and look through the "smart_data.log.
1. Log into your Genesis ZX web GUI by typing its IP address in a web browser that is on the same network as the Genesis ZX. Password is "admin" by default.
2. Once logged in navigate to "Diagnostic > Logs" and click on "Download all", it should take a few minutes to download the logs.
3. Once downloaded untar the file and navigate to "LOGS" and scroll down until you see "smart_data.log". Open this file to see the S.M.A.R.T data on your drives.
