H2testw is an app that allows the user to check USB drives and SD cards for reading and write errors. You can measure the degree of damage inflicted on partially broken/damaged USB devices by filling all the free space.
Another use can be observed when you unknowingly have a fake USB on which the data can only be written or read. It writes and then reads data to thoroughly check both operations to inform the user of errors and speed. There are two ways to fill in the data. You can choose to fill the entire available space or specify the size in MB that needs to be filled in for verification purposes.
Using the H2testw is easy and clear. After inserting a USB or SD card, launch the application and select the device by clicking Select Destination. Now select the options to fill in the data. It is recommended to save data to fill all the free space to look for depth errors.
