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. 16 Chapter 4 Serial and Parallel ATA Drive Guidelines and Features
