You can use recovery software like EaseUS, but because you deleted the header of the drive that tells the PC where everything is when you recover the drive, it will bundle all of X type file in the same folder. I once did this and it took 3 days to go through 1.4 million impulse files, and I still can't bring myself to sort them all out. It would take weeks.
EaseUS picked the partitions up but it is quite expensive (65CHF). It will not recover without the paid version. If I can save a bit I will!
I'm just a guy, not a company or OC competitor and OC don't do data recovery AFAIK.
