Yesterday night, I was playing SatSR, and my Wii made grinding noises and rumbled, so I switched to SMG and it was fine, then I switched back and it grinded again. I called Nintendo and the lady said: Her: "The disk drive has moving parts in it. It's normal." Me: "It's quite loud." Her: "Do you need to turn up your volume to hear the game?" Me: "Well... not really." So I kept playing. Today, I popped in NFS: Carbon and it did it louder, so I played until I realised it got louder a second time. I called Nintendo again: Me: "Yesterday, I followed the advice someone gave me about my disk drive's grinding noise, and it is getting louder." Another lady: "Is it only on one game?" Me: "No, it's on two that I tried, the one not grinding being SMG." Her: "What's your serial number?" Me: "LU________." Her: "Okay, we can send you a replacement then." *I put in SatSR* Me: "It seems to have stopped... Um... if it gets worse, I'll call back to get a replacement." Her: Well, you have 'til March to send it back in." Well, what should I do? Should I wait 'til it may get worse, or play it safe and send it in now.
