First of all, you should take into consideration, that having a RAW disk means that you have lost a partition in your disk. That leads into a conclusion that the recovery procedure might be little risky in terms of data.
I am an IT Officer/specialist, my job included many similar cases, and this might be solved as a piece of cake.
But i need you to understand that the risk of losing your data is there, even if it's below 10%.
Good luck.
