If data is important, you migh consider to STOP playing with a clients drive and send it to a proper data recovery center, or ask help from someone here.
Since it's a logic issue it will be possible for someone to assist you even remotely. For instance, i could very well recover the data on the drive remotely, by the net, if you are willing to pay some $$$$$ and assuming you didn't over-write the data on the drive.

Restorer Ultimate Network Pro can be run over the network (even internet) so that you can recover your client files from your home even if you are on the other side of the world.
