Simson Garfinkel wrote a while back that writing over data once is enough.
Here's a link to the article:

Here's the relevant part:

    In fact, there is no unclassified evidence that data on a modern hard
    drive can be recovered after it has been overwritten with just a single
    pass of random information. Some have made such claims, but no such
    recovery has ever been demonstrated in public. Today's hard drives are
    specifically designed not to work that way. When you save a new version
    of a Microsoft Word file on your hard drive, for instance, you want to
    get the new not the old version.
