Swapped to disc and now horrible scraping Help

Yea I intend on using the rotor as is. I also wanted to add in another odd bit. So I bought the set of Wagner MX215 pads on Amazon, got them and look at the defect? How in the heck does this get put into the box. I will also add, the box was sealed, and the 4 pads were shrinkwrapped as a unit. Some one had to handle this unit and stick it in the box right? Or is it all just computer people now? I ordered a replacement from Amazon, and those pads, came in the same box, and same shrinkwrap and were fine. In fact as I look at all the pads, they are all date stamped with the exact same date. Special note, the guy who put the wear indicator did his job, but then the person who's job is to put the clip on it, was stoned.
