L’éléphant et la girafe ne sont pas satisfaits de leur apparence. Ils aimeraient bien des oreilles plus grosses, un nez plus court, ou même changer de couleur. Heureusement, quand on est amis, on est parfaits l’un pour l’autre. Flashe le QR code au dos du livre pour écouter l’histoire en anglais. Un livre bilingue pour progresser en anglais.

Monitoring can determine when such failures are becoming more likely. 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 subsequent version of the standard improved failure prediction by adding an automatic off-line read scan to monitor additional operations.

Also, while earlier versions of the technology only monitored hard drive activity for data that was retrieved by the operating system, this latest S. A field study at Google covering over 100,000 consumer-grade drives from December 2005 to August 2006 found correlations between certain S. 39 times more likely to fail than a similar drive for which no such error occurred. Conversely, little correlation was found for increased temperature and no correlation for usage level.

That SFF standard described a communication protocol for an ATA host to use and control monitoring and analysis in a hard disk drive, but did not specify any particular metrics or analysis methods. ATA for communicating the same kinds of things. First introduced in 2004, it has undergone regular revisions, the latest being in 2011. The most basic information that S. It provides only two values: « threshold not exceeded » and « threshold exceeded ». Often these are represented as « drive OK » or « drive fail » respectively.
