Writing free space with only 1's or 0's

Hi,

I am using MS Virtual PC, and the software's help file states that if you write the free space of the virtual harddisk with only 1's or only 0's, you would be able to compress the virtual harddisk by a large ratio. My question is: How do you configure Eraser to do that??

Any help is much appreciated! :D
