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 and predict drive failures, and to carry out different types of drive self-tests.
Install
Ubuntu
$ sudo apt-get install smartmontools
Usage
Basic Info
-a: Prints all SMART information about the disk, or TapeAlert information about the tape drive or changer.-i: Prints the device model number, serial number, firmware version, and ATA Standard version/revision information. Says if the device supports SMART, and if so, whether SMART support is currently enabled or disabled. If the device supports Logical Block Address mode (LBA mode) print current user drive capacity in bytes.
