Just bought 2 x 2TB WD Reds for a Synology DS213. I decided to use WD's Data Lifeguard Diagnostic for the first time to make sure there are no issues. I was disappointed with the output of the extended test. It didn't say whether there were any bad sectors. Maybe that is a good thing (i.e. there were no bad sectors)? It just showed that it passed on the extended test. The test results also just showed check marks, meaning that it worked within normal operating parameters.
Am I missing something? Any other tools you recommend to test for bad sectors?
