Using smartctl to get information about your Hard Disk

smartctl controls the Self-Monitoring, Analysis and Reporting Technology (SMART) system built into any 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. This version of smartctl is compatible with ATA/ATAPI-7 and earlier standards
