Query: A+ Discs

This is my second purchase of 100 disc spindels of this type and I have yet to encounter a problem. The LG discs I used before these killed one of my drives while burning and that was only a 25 disc spindle. My other drive has lasted almost 200 burns so far with these discs. Pretty much the only kind I'm going to buy from now on. And yes they are identical drives installed at the same time by the same manufacturer.
