i have a nec cd/dvd+rw 2100ad. my system detects it, and i can use it for everything i need to use it for except burning dvd's. i run my dvd burning software, it goes through the whole process and even says the burn was successful, but when i try to veiw the dvd, it shows the disc as blank. i have tried flashing the firmware, but it says the drive is not detected "correctly". is there something i'm overlooking or is it time to smash it with a sledgehammer and go buy a new dvd burner?
