smartctl is a Linux command that 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 and predict drive failures, and to carry out different types of drive self-tests. "smartctl" can be used to know various information about the disks in your Linux system.


Device information : To know about the model, make and serial number of the disk, use "smartctl -a"

[root@geekyB ~]# smartctl -a /dev/sdb
