Use the S.M.A.R.T screens to view hard disk health indicators. Self Monitoring, Analysis, and
Reporting Technology (S.M.A.R.T) detects and reports the reliability of hard disks using standard
indicators (called “attributes”), to help you anticipate possible disk failures.
Note: The available S.M.A.R.T information varies from one hard disk vendor to another.
From the Internal Storage > Hard Disk screen, select a disk and click S.M.A.R.T to open the
screen as shown.
