[Drive Wiper non-functional]

You can only 'wipe free space' on your OS drive whilst using it. You could of course destructively wipe/nuke the drive outside of Windows with tools like DBAN or even CCleaner Portable via a BartPE CD, etc.

 

Awesome thanks - gonna try DBAN

Also it's a good idea to mention what your operating system is when you post.

 

Welcome to the forum

 

My OS is Vista Ultimate.

I see from your link that it's disabled "for safety reasons" - is that an option I can bypass? I plan on wiping and reinstalling Vista Ultimate. Yes C drive is my boot drive and the only drive on that laptop.

So I'm trying to wipe my drive and it won't let me - From the simple to Gutmann pass, my C drive is grayed out as is the Wipe button.

 

Please advise.
