Last week I posted about our Rock Band disc getting scratched. Not surprisingly I was unsuccessful getting EA to replace the disc which was a little surprising given that they replace the instruments with little pushback. I was expecting to have to buy a new disc but asked my son to see if he could track down a used one first.
It turns out the PlayNTrade near us has a disc polisher and for $3.20, they will attempt to repair your scratched disc. For $3, this is a no brainer as opposed to spending $35 (used) to $60 (new) for another disc. So we wandered on up to PlayNTrade to see if our disc could be fixed. After a couple spins in the polisher our disc looked pretty good. We took it home and SUCCESS, it works and we were able to play Rock Band all evening.
My nephew also brought along a scratched copy of Forza 2 he had and it too was polished and successfully plays now. As I stated above, for $3 it is a no brainer when you have a scratched disk.
