CrystalDiskInfo is a lightweight application that will help you keep your hard drive in good health.

You'll be able to look at your hard drives' main details, like brand, serial number, capacity, speed, and hours of use, all with a glance.

It is also compatible with S.M.A.R.T., so you can view a series of more specific details regarding statistics and errors.

The application allows you to establish security limits, and will activate a security alarm to warn you if any of them are reached, so you have a chance to backup your files before the drive fails.
