What is the cause? Is it bad media? I mean the discs run fine, but there is alot of clicking and stuff inside the Wii. Is this very bad? What should I do? It only occurs on backups. I use Verbatim (don't know where they are made) 16x certified. And backups also works on 1x. Does this mean if I continue the laser will die? I'm afraid to killl my Wii/laser, so please help Thanks.
