The 'dd' way is good enough unless someone is willing to to tear the drive apart in a lab.
I think this depends on how you use dd though. If you just do a single pass of zeroes, but fear someone will mount a multi million dollar electron microscope forensic analysis, then yeah, that might not be enough. But write from /dev/urandom with dd multiple times to the disk and you should be okay even with that extreme case. If I were worried about open-drive analysis of the drive I want to clean, then I'd be physically destroying the drive also. Put it in a kiln, get the oxy torch into it, etc.
