I did a little more research, You would have to have the same model logic board to do a swap like that or cannibalizing your ps3 to make the other work by swapping logic boards and chips. I would honestly go the easy route and have the drive itself repaired by people who actually do it for a living. BUT If you are confident in your skills to take on such a task, then by all means do it. There are tuts on it ( i don't have links ) and it could walk you through it but i there are some things needed..
1. Heat Gun
2. Soldering Iron
3. Solder Paste (Sn 63/Pb 37)
4. Flux
5. Isopropyly Alcohol
6. Desoldering Braid
This could be inacurate as i pulled the info from another source online (
