My drive has nothing on that orange part in the middle of the drive (like you can see in the pictures here) except for two QR codes; it has absolutely no markings/printed words model, name, brand, part number, etc. on the inside, except the manufacturing date 2012 stamped inside the black aluminum bottom case cover.
Hope this helps.
Thank you. My drive from 2012 ist fastened with a six-sided star-shaped Torx screw on the right side. The ones on the left side are black Philips screws and they are so tiny that they are hard to see in normal light. All I want to do is clean the drive from dust since it won't read DVDs anymore, while it has no problems with CDs at all. So now this Torx screw is another obstacle. I will have to waste more time & money buying an extra tool, thanks to Apple.
