10 Free Hard Drive Eraser Software Utilities

10 Free Hard Drive Eraser Software Utilities.  Data destruction software, sometimes called data sanitization software, disk wipe software, or hard drive eraser software is a software-based method of completelyerasing the data from a hard drive.

When you delete files and then empty the Recycle Bin, you don’t actually erase the information, you just delete the reference to it so the operating system can’t find it. All the data is still there and, unless it’s overwritten, can be easily recovered using file recovery software.

Data destruction software, however, truly does erase the data. Each data destruction program utilizes one or more data sanitization methods that can permanently overwrite the information on the drive.

If you need to remove all traces of a virus or you’re planning on recycling or disposing of your hard drive or computer, wiping your hard drive using data destruction software is the best way to protect yourself.

Note: Data destruction software is just one of several ways to completely erase a hard drive. Also, if a complete hard drive wipe isn’t wanted you’re after, check out my free file shredder software list for programs better suited for individual file destruction.

Below is a list of the best, completely free data destruction software programs available today:

1. DBAN (Darik’s Boot and Nuke)

Darik’s Boot and Nuke.

Darik’s Boot And Nuke, usually referred to as DBAN, is the best free data destruction software available.

DBAN is freely available in a ready-to-go ISO format so all you need to do is burn it to a CD or flash drive and then boot from it. The DBAN program’s menu interface is also very easy to use.

DBAN is an open source project.

DBAN is a great tool and should certainly be your first choice if wanting to completely erase a hard drive.

3. HDShredder Free Edition

HDShredder is a data destruction program that’s available in two forms, both of which work with one data wipe method.

Alternatively, you can install HDShredder to Windows like a regular program and use it for securely erasing data from a different drive like a flash drive or a different hard drive.

Note: Several additional features appear to work in this free edition until you try to use them, after which you’ll be told you need to upgrade to a paid version to use it.

Note: I was unable to use my mouse in PCDiskEraser even though a cursor was available. Also, I had to use the tab and space keys to move around within the program, which wasn’t a huge concern but did make using it a little harder than it had to be. 10 Free Hard Drive Eraser Software Utilities.
