Analyzing a Faulty Hard Disk using Smartctl - Thomas-Krenn-Wiki

The RAW_VALUE of the Current_Pending_Sector value indicates how many of the hard disk’s sectors can no longer be read and are waiting for re-mapping

We will start a short test in this example

— https://www.thomas-krenn.com/en/wiki/Analyzing_a_Faulty_Hard_Disk_using_Smartctl

smartctl -t short /dev/sdb s

— https://www.thomas-krenn.com/en/wiki/Analyzing_a_Faulty_Hard_Disk_using_Smartctl

The test results will be displayed by the command: smartctl -l selftest /dev/sdb.
