SMART ATA drives
The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for HP personal computers have
built-in drive failure prediction that warns the user or network administrator of an impending failure (crash)
of the hard drive. The SMART drive tracks fault prediction and failure indication parameters such as
reallocated sector count, spin retry count, and calibration retry count. If the drive determines that a failure is
imminent, it generates a fault alert.
