you wont... if it were a segate or wd is say go into a bestbuy and buy a drive, swap the boards and see if it works. there you could return the drive once you got your data. but samsungs are not sold in stores except from microcenter and frys. you can try buying the same model and year on ebay and swaping the chips, some times this works.
aside from that it takes data recovery of dismantling the HD.
