In all PATA and SATA hard drives on the market today, is already embedded features SMART (Self-Monitoring Analysis and Reporting Technology) that specifically detects the hard disk's health. In the SMART parameters were about 30 hard drives health, ranging from temperature, spin-out time, to seek error rate. From this data could be inferred if the hard disk on your PC is still healthy, or already ill.
To read this SMART data, we need specialized applications such as HD Tunes. The main functions of this application is measuring the speed of disk, but can be to read the SMART information, too. HD 15 Tunes will read SMART parameters, with 3 types of results, the current, worst, and the threshold. The definition of each outcome is:
· Current: current state of your hard disk
· Worst: the smallest number ever found in the previous generation hard drives
· Threshold: the limits below which shows the damaged hard drive
· Data: raw data from sensors or counters.
