You would be better off looking at better utilities if you really need to keep the data from being recovered.Nonsense. If you're worried about the zeroes just replace /dev/zero with /dev/urandom. Your "better utilites" don't work any different from that.I'd say it is very possible, otherwise organisations would not be offering these services, with "No Fix, No Fee Policies", at confirmed prices. There are a number of testimonials from existing customers: http://www.payam.com.au/hard-disk-data-recovery.htm If this is possible in Australia, I'm sure that the rest of the world has access to similar organisations ;-)
You're mistaken. Of course recovery is perfectly possible for data that was just deleted. However, we are talking about data that was not just deleted, but overwritten with zeroes or random data. That's a totally different story. Regards Ansgar Wiechers -- "All vulnerabilities deserve a public fear period prior to patches becoming available." --Jason Coombs on Bugtraq
