I took the old laptop of my sister a Presario 2811 EA and after upgrading RAM and HDD I realized that not all notebook dvd bays are the same. I purchased a NEC AD-7543 . Sadly I wasn’t aware that that my notebook bay is not for slim drives. But this is the tip of the iceberg. My main concern is that the totally different pin connection between my original and the new one (even different position) . I linked a photo I took with the new slim dvdr beeing on top of my old dvd drive. Anyone know what is this and where can I get a new drive for my laptop?
