Secure delete util?

[kirkbross]

I'm looking for a utility to securely delete previously deleted files, but only the FREE space on a drive -- not the entire volume which I know Disk Util can do with a 7 pass or 35 pass.

Any suggestions?

Der. Thanks... for some reason I thought the Disk Utility only erased entire volumes. I didn't read carefully enough and assumed I'd need to buy something. I love Mac OS.
