The software program works by writing, reading and verifying test data that is written on the selected device. Existing files that are already stored on the device will not be harmed if the tests do not find any defects. This does however mean that existing files can be harmed if defects are found on the device. It is therefor recommended to clean the device before running the test program.

The device integrity and size test will write files with a size of one Gigabyte to the selected storage device. All files that are written to the device will be named x.h2w with x starting with 1 and counting up. The software will then verify the files that have been written to the medium and display a report once the verification has been completed.

The program will display a rating and a detailed report on the data that was written correctly and incorrectly. The tool can for example be used to test if the advertised capacity of the USB flash drive or hard drive has the correct size.

H2testw is compatible with Windows XP, Windows Vista and Windows 7 and does not require administrative rights.

They store the data that you are working with and a failure or defect could lead to data loss sometimes without the possibility of recovering the data. Backups are of course a good idea but monitoring the hard drives performance is another method to check if it is likely that your hard drives might be at the end of their life cycle.

HDD Health monitors some of the important key factors of modern hard drives such as temperature, read and seek error rates and performance. If one variable reaches a critical value you are informed by HDD Health and should take counter measures. The first would be making a reliable backup of your hard drive, the second thinking about ways to fix the problematic values.

If the temperature for example is reported to be of critical value you should think of improving the air flow of your case, get hard drive coolers, add more fans or move from air cooling to water cooling. Other errors such as read write errors prove to be more complex. They could be temperature related of course but if the temperature is not critical it is an unlikely reason.

So, the main advantage you get is to receive a report before a crash or hard drive failure occurs giving you time to react and backup your data.
