Linux smartmontools and linuxsmartmontools

Smartmontools is an open-source Disk control and monitoring tool that runs on Linux, Unix, BSD, Solaris, Mac OS, OS/2, Cygwin, and Windows, it can also run from the boot disc or boot floppy disk, supporting ATA/ATAPI/SATA-3 (to-8) bit hard disk and SCSI hard disk, as well as tape equipment, its hometown is smartmontools.sourceforge.net. In fact, it is a software package, including two utilities: smartctl and smatd. The hard disk it monitors must have S. m.A. r. T feature. Currently, all hard disks have this feature, but this feature is usually not enabled by default. There are two ways to enable this feature: 1) enable this feature through BIOS (option 2) use the smartctl command. It can be used to test the health status of the hard disk and provide early warnings before a fault occurs.

Install in Ubuntu:

sudo apt-get install smartmontools
