Linux Control and Monitor Utility for Smart Disks

Smartmontools (S.M.A.R.T. Monitoring Tools) is a set of utility programs (smartctl and smartd) to control and monitor computer storage systems using the Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) system built into most modern (P)ATA, Serial ATA and SCSI hard drives.

Smartmontools displays early warning signs of hard drive problems detected by S.M.A.R.T., often giving notice of impending failure while it is still possible to back data up.
