I am looking to buy a DVD burner for my Gateway 500S series computer. I think everything my system only uses the IDE type interface but I am not certain. I have seen some Dual Layer DVD burners that were listed as being ATA type, and they are a few dollars cheaper than the IDE type. Can someone tell me how to Identify the connector types for my system and also whether I can get a ATA to work with an IDE type interface? Thanks John T McDougald
