FREE HARD DRIVE TESTING PROGRAMS are very important tools especially when it comes to addressing issues like disk errors. Such errors may include frequent messages popping up while running software, repeated program crashes, humming from the drive, and strange noises such as clicking.

Such issues may warrant a complete replacement of the hard drive or one would have to engage a hard drive repair software program. Some of the most effective hard drive diagnostic software options are:


This is one free hard drive diagnostic software available on most hard drives. It is very easy to use, having two HDD testing functions. One can test more than one drive consecutively and a person can also perform a deep test for better results. The software though cannot be employed in scanning a hard drive where Windows is installed and so it works on Windows operating system only.

Samsung HUTIL

Samsung HUTIL is a free hard drive diagnostic utility that’s not too difficult to use. It is used for testing hard drives notwithstanding the operating system installed. The program can be run from a bootable floppy disc. However, the software only tests Samsung HDDs. The interface is completely text, there are no buttons to click. A working computer would be needed to set up the program.
