In order to make the RMA easier for you, you can run the extended test in the Data LifeGuard Diagnostics tool.

You don’t need to run the full test. Just abort it, when it gets stuck at around 40%. This will probably create a new value in the first line of the SMART-report (Raw Read Error Rate). If this value is below the treshold value, you are eligible for a RMA.
