-[[https://en.wikipedia.org/wiki/S.M.A.R.T.|SMART]] is an acronym for //**S**// elf //**M**// anaging //**A**// nalysis //**R**// eporting //**T**//  echnology. For many years, PC's or laptops have been delivered with a HD (Hard Drive). HD's contain a spindle motor to rotate the disk(s), and a positioning motor to locate heads over the disks. While the disks are spinning the heads detect or generate magnetic information on the media. Electronic devices and firmware in the HD are designed to monitor and/or tolerate marginal behavior of the HD components. The HD is also capable of reporting correctable or uncorrectable behavior. This implies the HD contains devices that manage the components in the HD. There is a standard known as [[https://en.wikipedia.org/wiki/S.M.A.R.T.|SMART]] (Self Managing Analysis Reporting Technology) that defines data the HD can report about internal characteristics. There are programs for Windows and Linux that allow you to see SMART information. Some of the SMART data can indicate the HD should be considered for replacement before a catastrophic failure.+[[https://en.wikipedia.org/wiki/S.M.A.R.T.|SMART]] is an acronym for //**S**//  elf //**M**//  anaging //**A**//  nalysis //**R**//  eporting //**T**//  echnology.

 I am not aware of Windows or Linux paying much attention to SMART data in such a way as to warn the user before the HD is problematic. However, I have observed that a HD that is not accessible with Windows (will not boot or show data), does work "good enough" with Linux to allow access to SMART statistics and recovery of data. I am not aware of Windows or Linux paying much attention to SMART data in such a way as to warn the user before the HD is problematic.

 So how can a consumer differentiate between //**soft**//  errors (errors that were corrected), //**hard**//  errors (uncorrected errors) and //**soft**//  errors that should indicate //**Replace The HD**//  ? So how can a consumer differentiate between //**soft**//  errors (errors that were corrected), //**hard**//  errors (uncorrected errors) and //**soft**//  errors that should indicate //**Replace The HD**//  ?
  
-Gsmartcontrol can display the contents of a LOG of HD events. If the LOG displayed by gsmartcontrol shows messages that are the color <font inherit/inherit;;#e74c3c;;inherit>RED</font>, the HD probably needs to be replaced.+Gsmartcontrol can display the contents of a LOG of HD events.

 SMART data includes statistics about corrected errors. Corrected errors can include //**positioning errors**//  ( The HD determined that it positioned the heads in the wrong place) and //**media errors.**//  (The HD determined a part of the disk surface is //**incapable**//  of storing data). SMART data includes statistics about corrected errors.
