Analyzing a Faulty Hard Disk using Smartctl

Under Linux, you can read the SMART (Self-Monitoring, Analysis and Reporting Technology) information from the hard disk using smartctl. In this example, we will show how to analyze a defective hard disk. The hard disk in this example can no longer read several sectors and is therefore defective. It has to be replaced.
