I just bought a 10 pack of emtec dvd-r's and I have 3 nice shiny, expensive coasters on my hands already. When the burn process gets to about 90% I get the error message: "scsi target error". I upgraded nero to the latest version and still no luck. When I was using TDK discs I had no problem, I was using nero and the same exact hardware and software configuration. Does this sound like a disc problem to you?
