CBL Data Shredder is a free and easy to use data destruction program that can be run both inside and outside of Windows, making it a very versatile program.
Hide your secrets FOREVER! – Securely erase data
When you run this program outside of Windows, you can use it to destroy a hard drive that has an operating system installed on it. From within Windows, this utility can completely erase any internal or external drive except the one you use for Windows (usually the C: drive).
CBL Data Shredder comes in two versions, both of which are useful for different scenarios. The first is a bootable program that can be used on a floppy disk or a data disc, and the other is a regular program that works on Windows 10 through Windows XP (it doesn't work for me on Windows 11).
The bootable program comes as a floppy disk program or ISO disk image. It is useful for wiping the hard drive on which an operating system is installed. For example, if you want to wipe a Linux or Windows hard drive, use this bootable method to wipe the drive.
