Every hard drive has S.M.A.R.T. software that detects internal drive failures.
However, most manufacturers disable these notifications hoping that your failing hard drive will work well enough to get you through the warranty period.
Drive Adviser bypasses the manufacturer lockouts to read the drive’s S.M.A.R.T. information. We then calculate your drive’s health based on the failures it has experienced over time.
100% is a perfect drive and anything less is a drive in failure status.
