When my son starts his laptop a message appears saying: SMART failure Predicted on hard drive. Immediatly back up your data & replace your hard drive. A failure may be imminent. Press F1 to continue. Yet when he went into Device Manager It said The device is working Properly. Which one of these should he take notice of.Thanks Mac
"This device is working properly" only means windows can currently see and access the drive.
Through the SMART system, hard disk drives incorporate a suite of advanced diagnostics that monitor the internal operations of a drive and provide an early warning for many types of potential problems. When a potential problem is detected, the hard drive can be repaired or replaced before any data is lost or damaged.
The S.M.A.R.T. system monitors the drive for anything that might seem out of the ordinary, documents it, and analyzes the data. If it sees something that indicates a problem, it is capable of notifying the user (or system administrator). S.M.A.R.T. monitors disk performance, faulty sectors, recalibration, CRC errors, drive spin-up time, drive heads, distance between the heads and the disk platters, drive temperature, and characteristics of the media, motor and servomechanisms. The errors the system can detect can be predicted by a number of methods. Currently the SMART system can detect about 70% of all hard drive errors.
Try running Chkdsk /f or Chkdsk /r or scheduling a disk check on bootup.
This may repair the errors and stop SMART from giving the message if not then replace the hard drive.
