Several companies make products that "security erase" your drive.
They first overwrite it with strings of random bits, then they erase
that.

This not the securest method, however. The securest method of
erasing a hard drive is taking is apart and using the platters as
drinks coasters. Or otherwise physically destroying the media.

I read an article yesterday about how NIST have developed a
machine that can see multiple layers of data sitting on a drive. They
can go past the format you did and see what used to be there. The
FBI is using prototypes. :-)

Ontrack are one of the most respected hard drive people in the biz.
