![]() ![]() ![]() (2003) comments that the technology has gone through three phases: These may include increased heat output, increased noise level, problems with reading and writing of data, or an increase in the number of damaged disk sectors. While the eventual failure may be catastrophic, most mechanical failures result from gradual wear and there are usually certain indications that failure is imminent. Mechanical failures account for about 60% of all drive failures. Unpredictable failures which occur without warning due to anything from electronic components becoming defective to a sudden mechanical failure, including failures related to improper handling.Monitoring can determine when such failures are becoming more likely. Predictable failures which result from slow processes such as mechanical wear and gradual degradation of storage surfaces.Hard disk and other storage drives are subject to failures (see hard disk drive failure) which can be classified into two basic classes: data indicates a possible imminent drive failure, software running on the host system may notify the user so action can be taken to prevent data loss, and the failing drive can be replaced and data integrity maintained. Its primary function is to detect and report various indicators of drive reliability with the intent of anticipating imminent hardware failures. Self-Monitoring, Analysis, and Reporting Technology ( S.M.A.R.T., often written as SMART) is a monitoring system included in computer hard disk drives (HDDs) and solid-state drives (SSDs).
