Hey guys, so i was doing some Harddrive cleaning, i put a bunch of garbage file son crappy Office Depot badged Ativa DVD +R media. This is the second of the 20 Ativas i burned: That patch there isn't ketchup. It's rough "burn residue" that i found on the disc after the burn had failed. wow! i was scared this killed my baby Pioneer 111D, but thank jesus it didn't. This is why u should avoid crap media, because it might just poop your drive. i got lucky this time. When burn fails and leaves a physical residue- that's some very very serious failure in the drive and some very bad media. I would have been very unhappy if this disc killed my drive. oh and btw i have burned well over 500 discs, and this is disc related coaster Number 3. Good Luck with burning discs everyone!
