Self-Monitoring, Analysis, and Reporting Technology, or S.M.A.R.T., is a monitoring system for computer hard disks to detect and report on various indicators of reliability, in the hope of anticipating failures.

[edit] Background Fundamentally, hard drives can suffer one of two classes of failures:
Predictable ones, when some failure modes, especially mechanical wear and aging, happen gradually over time. A monitoring device can detect these, much as a temperature dial on the dashboard of an automobile can warn a driver — before serious damage occurs — that the engine has started to overheat.Unpredictable ones, when other failures may occur suddenly and unpredictably, such as an electronic component burning out. Mechanical failures, which are usually predictable failures, account for 60 percent of drive failure(source). The purpose of S.M.A.R.T. is to warn a user or system administrator of impending drive failure while time remains to take preventive action — such as copying the data to a replacement device. Approximately 30% of failures can be predicted by S.M.A.R.T.[1]
pctechguide's page on S.M.A.R.T. (2003) comments that the technology has gone through three phases:
"In its original incarnation SMART provided failure prediction by monitoring certain online hard drive activities. A subsequent version improved failure prediction by adding an automatic off-line read scan to monitor additional operations. The latest SMART III technology not only monitors hard drive activities but adds failure prevention by attempting to detect and repair sector errors. Also, whilst earlier versions of the technology only monitored hard drive activity for data that was retrieved by the operating system, SMART III tests all data and all sectors of a drive by using off-line data collection to confirm the drive's health during periods of inactivity."
[edit] History and predecessors The industry first hard disk monitoring technology was introduced by IBM in 1992 in their IBM 9337 Disk Arrays for AS/400 servers[2] utilizing IBM 0662 SCSI-2 disk drives. Later it was named Predictive Failure Analysis (PFA) technology. It was measuring several key device health parameters and evaluating them within the drive firmware. Communications between the physical unit and the monitoring software were limited to a binary result - device is OK, or is likely to fail soon.
Later[3] another variant was created by computer manufacturer Compaq and disk drive manufacturers Seagate, Quantum, and Conner, which was named IntelliSafe. The disk drives were measuring the disk health parameters and the values were transferred to the operating system and an user-space monitoring software. Each disk drive vendor was free to decide which parameters are to be included for monitoring and what are their thresholds. The unification was at the protocol level with the host.
Compaq submitted their implementation to Small Form Committee for standardization in early 1995[4]. It was supported by IBM, by Compaq's development partners Seagate, Quantum, and Conner, and by Western Digital who did not have a failure prediction system at the time. IntelliSafe's approach was chosen as it gives more flexibility. The resulting jointly-developed standard was named S.M.A.R.T.
