HDDScan is a versatile tool primarily focused on surface testing and diagnostics with a portable format, while CrystalDiskInfo excels in S.M.A.R.T monitoring and real-time drive health reporting but requires installation. Both tools serve essential functions for hard drive management, but their features cater to different user needs.
