I see now that there are many ways of extracting that low-level residual data. But you would really need to have data someone REALLY wants for them to be willing to try most of those techniques. Frankly, if the deleted data is that critical, I would backup the drive, buy a new one (they are cheap enough these days) and restore from tape. Then use the old one as a doorstop or melt it down somewhere. -jm "I said he'll flip you.
