/usr/sbin/smartctl – controls the Self-Monitoring, Analysis and Reporting Technology (SMART) system built into many ATA-3 and later ATA, IDE and SCSI-3 hard drives. The purpose of SMART is to monitor the reliability of the hard drive, give detailed information and and predict drive failures, and to carry out different types of drive self-tests. With “-a” option it prints all the SMART information on the disk.
