CrystalDiskInfo is an app designed to help you keep your PC’s hard drive healthy. The program, which supports S.M.A.R.T. technology, helps you detect and prevent future disk surface errors so that you can take timely action before data loss becomes irreplaceable.

CrystalDiskInfo shows you all kinds of detailed information about the hard disk, from the brand and model to the buffer and cache size, the serial number, or even the firmware it uses.

The program uses a color scheme to warn you about the dangerousness of the disk’s state, so if you notice that the temperature or some specific action exceeds the limits of what you consider appropriate, it may be time for you to get to work and make the appropriate backups.
