7 dvd writers. 2 Asus,2 Mad dog, 2 unbranded and 1 is a H-L Data Storage. 4 are Sata and 3 are IDE style. At least one is a lightscribe. I don't have the time to test them but I know there are a couple that had ejection problems where you needed to tap the front to get them to eject. One has part of the front cover missing. As is but they should work, just don't have the need or time for them. I can deliver in the Yucca Valley, Joshua tree and 29 Palms area (including the base).
