I am having the same problem... and from what I have read online, it appears this is not uncommon. I doubt it is the drive.
I installed everything beautifully, but when I insert the OSX disc that came with my Mac Pro (per the apple instructions), it won't recognize the disk. Says it has 0kb on it.
When I watch videos of people doing this on Youtube it auto-launches and works fine.
One post suggested I update my Windows7 software as their was a hotfix to address this issue specifically.. so I spent 45 mins and did that. Still doesn't work.
Like many people I have seen, I would just love for apple to let us download the drivers and move on (just like you can do with printers, scanners, etc..) but for some reason I have seen that referred to as "illegal" on forums unless apple provides them to you. i am sure there is a huge black market for Mac drivers on Windows
So, I have a Mac Pro, Macbook Pro, iMac 24" and Windows on my Mac Pro will recognize NONE of the startup disk.
What gets stranger is when I open those disc on using the OSX, I don't see bootcamp in the utilities folder as it says online. Could the problem be that simple? The files aren't on the disk that Windows can use? Very confusing... (and no, I don't live near an apple store).
I feel helpless...
I have no idea how I am going to get the drivers installed into Windows 7 at this point short of calling apple and paying for a discussion.
