I also agree to restore your needed data back for free at first with some data recovery freeware available online. In fact, personally speaking, except Recuva, there are also other drive data recovery freeware that always do a good job.

But, if this really doesn’t make a sense, you may have to ask for a professional data recovery service from a data recovery company or expert, if the inner saved data is very, very important.
I hope you could learn a impressive lesson to back up everything important on separate drives after experiencing this trouble.
