No there isn't.

It's been proven again and again that you cannot reliably overwrite
data on a magnetic media.  In particular the difference in read/write
geometry and lack of fine control over head placement makes this
impossible.

The only reliable way to loose data is to encrypt them and throw the
key away.

Live with it.
