Depends on exactly the type of 'dump' it took. In any case you can not just swap in a new drive straight up, the drive and motherboard are keyed together.
Your drive may just need a new laser or something else to get it going again, just depends on what's really wrong with it as to the best way to go about fixing it back up. If you plan to get a new Samsung drive and your drives Logic board is still good, and it should be unless you tried to flash it and wrecked it, in which case you're in for way more work to replace it and possibly not even being able to depending on the damage that's been done. If ya were to get another Samsung drive, version doesn't matter (ms25 or ms28) you can just swap over your Logic board from your drive to it and be done, provided your original drives board is in good order.
