Wiping HDDs

[JLK03F150]

I have a bunch of old 3.5" hard drives that need to be securely wiped. What's a good, (relatively) fast, free program to do this? I'll be using a Vista 32bit PC with a Pentium D to do this project.
Thx

Haven't used it lately, but has always been effective in the past........ymmv

DBAN is a self-contained boot disk that automatically deletes the contents of any hard disk that it can detect. This method can help prevent identity theft before recycling a computer. It is also a solution commonly used to remove viruses and spyware from Microsoft Windows installations. DBAN prevents all known techniques of hard disk forensic analysis. It does not provide users with a proof of erasure, such as an audit-ready erasure report.
