I want to swap my CD-RW in my Gateway M275 with a DVD-RW instead. I did some searching and an OEM replacement is $150+. So I went to my small local computer shop and the guy at the counter warned me that if I don't get the OEM drive that it might fry my motherboard.. or the drive socket on the board at best leaving me screwed so I best get the OEM drive. Does this sound logical at all? I did some searching and found that people have replaced the "OEM" Matshita UJ-812B, although in other types of laptops (Sony Viao specifically), with a Optiarc AD-5540A which I found for about $40. Can anybody give me some insight here? I've never really messed around with laptop internal hardware and the guy at the store made me feel like I shouldn't go a step farther.
