Hard Drive Smart Test Error Codes
Contents |
(Self-Monitoring, Analysis and Reporting Technology; often written as SMART) is a monitoring system included in computer hard disk drives (HDDs) and solid-state drives (SSDs)[1] that detects and reports on various indicators of drive reliability, with how to fix smart hard disk error the intent of enabling the anticipation of hardware failures. When S.M.A.R.T. data indicates a smart test failed error code 303 possible imminent drive failure, software running on the host system may notify the user so stored data can be copied to how to fix smart hard disk error hp another storage device, preventing data loss, and the failing drive can be replaced.

Monitoring can determine when such failures are becoming more likely. Unpredictable failures, how to fix smart hard disk error mac happening without warning and ranging from electronic components becoming defective to a sudden mechanical failure (which may be related to improper handling). Mechanical failures account for about 60% of all drive failures.[2] While the eventual failure may be catastrophic, most mechanical failures result from gradual wear and there are usually certain indications that failure is imminent. 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. A field study at Google [3] covering over 100,000 consumer-grade drives from December 2005 to August 2006 found correlations between certain SMART information and actual failure rates. In the 60 days following the first uncorrectable error on a drive (SMART attribute 0xC6 or 198) detected as a result of an offline scan, the drive was, on average, 39 times more likely to fail than a similar drive for which no such error occurred. First errors in reallocations, offline reallocations (SMART attributes 0xC4 and 0x05 or 196 and 5) and probational counts (SMART attribute 0xC5 or 197) were also strongly correlated to higher probabilities of failure. Conversely, little correlation was found for increased temperature and no correlation for usage level. However, the research showed that a l
