Self-Monitoring Analysis and Reporting Technology

Self-monitoring Analysis and Reporting Technology (S.M.A.R.T) is a monitoring system whose main function is to predict failure in a computer. External SATA or e-SATA support this technology. It is also contained in Hard Disk Drivers and Solid-state Drivers in side a computer.

SMART is like a boundary between the Basic Input Output System and the computer’s storage device. When SMART technology is activated, the input-output system can execute data from the internal storage and take the decision about sending a warning message regarding the failure of the internal storage. Hence, what SMART actually does is, sending the user a warning message regarding the inability of the internal storage, while the user still has the scope to repair it.

Therefore, this technology takes an important part in protecting the user information and reduces the probability of uncertain failures which are caused due to fault in the storage. The SMART technology helps the user by making them aware of the probable bad conditions or inability of the device.

Like any other technology, SMART too comes with a set of attributes. These attributes are detected by the manufacturer in order to guide the users with SMART’s highest and lowest tolerance levels. Here I’m discussing those attributes to make you aware.

Self-Monitoring Analysis and Reporting Technology

  • Identifier- it states what attribute actually is.
  • Raw Data – it refers to the actual measured value. It is later executed by an algorithm, by developers and manufacturers.
  • Threshold –the level or value at which the attribute fails.
  • Value – the current situation of the attribute. This one too is measured byalgorithm.
  • Worst – from the name it is clear that it detects the worst possible value for the attribute.


  1. Motherboards too can predict failures sometimes and can create warning message accordingly. But this feature is not available to every motherboard. SMART is therefore created for the sole purpose of predicting failure and making the users aware of the probable failure by warning message in advance.

Some of the attributes mentioned above might mean different for different manufacturers or vendors. So, SMART is, therefore, manufacturer specific. This is the reason why some manufacturers’ SMART lacks some of the basic features, like, the heat sensor or might lack one or two attributes.

  1. All SMART activated motherboards may not be compatible with all SMART activated drivers. As there are so many power connectors to connect hard drives, like, SATA, SSA, PATA etc. it is almost impossible to figure out whether the Self-Monitoring Analysis and Reporting Technology would work perfectly or not. Sometimes it may also happen that your computer is not being able to see the warning messages sent by the SMART. This happens due to the condensed placement of the driver and the interface.This was pretty much a brief overview ofSelf-Monitoring Analysis and Reporting Technology. But there are more to it. You still have a lot to know regarding the Self-Monitoring Analysis and Reporting Technology, how it works, which power connector supports this technology and so on
