A great program to monitor the temperature and health of your drive
Pros & Cons:
CrystalDiskInfo is a great monitoring program that can warn you if the temperature and the health of your drive is deteriorating.
Its default temperature warning is set to 50 °C/122 °F which can be adjusted. It offers graphs of the accumulated S.M.A.R.T. information. It had no problems telling me almost everything about my external USB hard drive.
I like that it lists the Power On Count as well as the total Power On Hours. This is Open Source software. There is a portable version as well as an installer. Overall this is one of my favorites.
