Final answer:
HWiNFO can provide S.M.A.R.T attributes of a hard drive, such as reallocated sector count, read error rate, and drive temperature to diagnose issues. Access this information by clicking on the 'Sensors' button in HWiNFO.
Step-by-step explanation:
HWiNFO is a diagnostic and monitoring tool that can provide a wealth of data to help diagnose a potentially failing hard drive. When using HWiNFO, the specific type of data that can be useful includes the S.M.A.R.T (Self-Monitoring, Analysis, and Reporting Technology) attributes, which provide details on various aspects of the drive's health and performance. These may include parameters such as the reallocated sector count, read error rate, and drive temperature, among others. To access this data, you will need to open HWiNFO and click on the 'Sensors' button, which will take you to a screen displaying live sensor data from all detected components, including hard drives. Look for the section pertaining to your hard drive and review the S.M.A.R.T data presented there.
