View source for SMART utilities

From smartctl(8):

"the Self-Monitoring, Analysis and Reporting Technology (SMART) system [is] 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 and predict drive failures, and to carry out different types of drive self-tests"

The smartctl (and smartd) programs belong to the smartmontools package.

'''smartctl -a /dev/hdX''' will report on a disk's self-monitoring data, to reveal signs of impending failure. It will also print the results of self-tests performed by the drive.

'''smartctl -t long /dev/hdX''' will initiate an extended self test.

For Linux libata disks (e.g. SATA devices treated as SCSI devices, i.e. those named /dev/sdX) you need to add '''-d ata''' to the smartctl command line.
