Failure in the hard disk refers to the condition in which the files or data stored in the system becomes at risk or inaccessible due to hardware malfunction. There are lots of factor affects the stability & the function of the hardware. Since hard disk is composed of mechanical & electronic component, it is likely that it will affect the function of the hard disk once a certain component failed. Your S.M.A.R.T (Self Monitoring, Analysis and Reporting Technology) is probably enabled on your CMOS. It is designed to detect or indicate an upcoming failure in the hard disk. If you are getting this error, it is recommended that you replace your hard disk. If it still under warranty then claim for a hard disk replacement. If you still have data in the hard disk it is also recommended to make a back up of your files.
If you are receiving that message on your computer that means your hard disk’s S.M.A.R.T. system detected a fault that can cause a possible device failure. The drive’s S.M.A.R.T. system doesn’t throw that message on normal problems. You only get that if the problem is severe where the device may stop functioning.
Since you are receiving this message, you should backup your data immediately because it is a sign that the drive may stop working anytime. When there is a S.M.A.R.T. failure and the drive stops functioning, there is no way you can make it work again and the possibility of recovering the data is less.
That’s why, if you can still access the contents of the drive, you should copy the data to another separate drive. S.M.A.R.T. stands for “Self-Monitoring, Analysis, and Reporting Technology”. It is a diagnostic method developed originally by IBM and introduced with the ATA-3 specification which, at that time, referred to as “Predictive Failure Analysis”.
The technology was originally developed for IBM mainframe drives to provide advanced warning of drive failures. Based on this diagnostic method, Compaq announced “IntelliSafe”, which was submitted to the ATA/IDE standards committee, and the resulting standard was named “S.M.A.R.T.”
