DiskRadar is a very complete hard drive monitoring tool. There are quite a few things that this app monitors. It can check the health and temperature of your drives. This can be a very useful tool to determine the overall health state of your drives, which can then help you to avoid data loss caused by a failing drive. Many sensors are checked during the health diagnostic mode, and the application logs the values to compare them with previous ones. Some of the available information about sensors is throughput performance, raw read error rate, spin up time, start stop count, power on hours, and many more.

Other than checking on your hard drive's health and current state, DiskRadar is also very good at graphically displaying how much space is used on your drive, how often files are accessed, and which folders have the most files in them. To be able to do this, the app carries out a scan that can take anywhere from a few minutes to a half hour, depending on your drive speed and size. After the scan is done, you will see all this information in a nice graphic that you can interact with. There is a slider at the bottom of the screen that lets you select those files that are used more or less frequently. On the right, you will see a list of the folders that take up the most space.

In conclusion, DiskRadar is a great tool for anyone who wants to keep an eye on the state of hard drives, or anyone who is looking to find where his hard drive space has gone.

DiskRadar is an app to 'take care' of your drives. I am impressed by colourful maps of drives. The program is quite easy to use, the interface is straightforward. However, it lacks repair functions.
