Attached below are some high quality pictures from an anonymous (but trustworthy) source of the three sets of DVD drives found in the X-Box 360, we have the Hitachi, Samsung-Toshiba, and what we believe to be the newly released Phillips drive. From the pictures below, you can now easily determine which one you have!
How do you know which version of the Hitachi drive is installed in your 360? I see that there are firmwares patches for various model number of Hitachi drives. Is there also more than 1 version of the Toshiba?
There is only 1 known version for the Toshiba-Samsung and Phillips. There is also NO WAY to know what of the 7 versions of the Hitachi-LG drive you have without opening your case and looking at the sticker. Sucks for sure!
