I'm sorry Marco, but I think what you've said is "bullshit", as well contacted several "so called" data recovery organizations, after admitting to have "zeroed" the drive contents - They said recovery wasn't possible..
While it "might" be possible to get miscellaneous data off of a drive, it would likely be cost prohibitive (if even possible..). But let's see how new_guy(aka Brad)'s quest goes.. perhaps he can post any documents/paper would returned by the company.. -Nix Fan.
