Just burned a Ritek G04 unbranded purchased from Bigpockets and got my first coaster!! Im not saying these aren't good disc, since i have had over 100 burns without any coasters, but here are the details of this bad burn anyway: I have however, checked the rest of the Spindle and no other discs look to be in a bad way. Some dye was missing off this disc. Chris_X_X_X_X_X_[small]Im gonna find you, and im coming to get YOU! [/small]
