It displays an incredible amount of simple and advanced disk information, and may always be running in the background. This includes temperature readings, read/write errors and power management tools, running at all times of the day.
General Information on your drive.
Advanced Diagnostic of your drive.
HD Tune is a much simpler hard drive disk scanning utility that has benchmarking, advanced diagnostics, similar to Crystal and a disk scanning utility, very similar to the Windows version, but can be run in real-time. It also includes real-time temperature monitoring.
HD Tune also uses the SMART based technology and has already been a help to myself. I knew that my hard drive was on the brink, and this was the first utility to confirm that. You’ll see my errors below. I wasn’t even able to run the benchmarking tool on my system drive. The screen shot below is for my data drive. It also supports all connection types.
HDD Health is another similar product that can help you predict and prvene hard disk failure. It includes temperature and real-time monitoring, but includes a health indicator, simply by percentage and nothing more. It does include the same advanced diagnostic tools as the other SMART utilities as well.
Extended Drive Information
HDD Scan not only includes many SMART diagnostic utilities, but other disk utilities as well. It includes many advanced testing modes, such as reading, writing and erasing in linear. In comparison to the other products, HDD Scan might get you more bang for the free buck.
