I've recently fitted a Crucial M4 SSD to my 17" 2009 MBP and everything works perfectly under Lion. However I can't see the Superdrive in Windows 7 (Bootcamp). High level summary of the process I followed (Clean install of Lion and Win7 bootcamp): 1. Fitted SSD to HDD bay 2. Installed Lion and Windows 7 via usual Bootcamp process 3. Removed internal Superdrive, fitted my old HDD in an Optibay clone. 4. Fitted Superdrive to an external USB enclosure. Everything works perfectly in OS X Lion. But in Windows 7, my Superdrive isn't working properly. Basically, in Devices, there is something showing up as 'USB to Serial ATA Bridge' which only appears when I plug in the USB Superdrive. So that must be Windows 7 recognising the tiny PCB inside the Superdrive enclosure - all good so far. It also identifies it as an Optical drive, and when I right click on the icon, in the Hardware tab it even shows the drive model, which is a Matshita UJ-868. However, when I insert a DVD, or any kind of disc, e.g. Windows software etc, it spins up, but then slows down, and eventually just shuts down again. The above device remains present throughout in Devices. I downloaded the latest Apple Support software for Win7 as part of the Bootcamp process, and have also downloaded the latest Apple software for Windows 7 using the updater in Windows. Could it be a driver issue? In Devices, under Hardware, it seems to be using a generic windows driver (C:\Windows\system32\DRIVERS\cdrom.sys). Help! This is driving me mad. There must be loads of people who have done the same thing as me (i.e. converted an internal superdrive to a USB one) - surely it is something simple? Any help and advice would be much appreciated !
