Undoubtedly, DBan is the most widely used software. When you go to DBan website and navigate to the download page, you can see the latest release of the program.

It contains different methods for wiping off data from the hard drive.


The KillDisk program is available in two versions namely, Free and Professional. The Free version is on par with DBan program. However, the Professional version is better than DBan as it brings to you many useful options. The Professional version is available in three types DOS+Windows Suite (priced below $60), Windows version (priced below $50) and DOS version (priced below $40). The free version will delete the data off from the hard disk by writing zero’s only once. If you purchase the Professional version, you can use over 15 types of options to delete data. The app can be used directly in Windows or by launching Command Prompt (DOS). You can also create a bootable media and wipe off all that you have stored on your hard drive.

Disk Wipe

Disk Wipeis a free Windows based software (that means it is not available in DOS version). You can launch it inside your Windows OS only to get rid of data stored in hard drive, USB drives, external hard drives, and memory cards that support FAT, FAT32, NTFS file systems. After downloading it, you can directly use the program without any installation. The size of the app is very small which makes it possible for you to store it in your USB drive or send it to your friends through email.


The app is just like Disk Wipe. It is also a freeware that can be used only inside Windows. Good thing is that the app is updated regularly. It can erase data from all kinds of storage drives that support Windows. This app does not provide you with advanced options as compared to the apps mentioned above. Hence, it is not the best option that you can rely on.
