Why Microsoft would choose to do this is completely insane. How can anyone share files with other Operating Systems (Mac OS X or Linux OSes), if the other OS'es cant even read the disc. I have a MacBook running OS X (10.4.10), the disc showed up as unreadable by my computer, not even File Salvage (by Sub Rosa Soft) could recover anything (I got an error showing that two blocks back-to-back were bad). I found out which OS the friend had used, loaded my copy of Vista and the CD showed up fine. Vista security problems are bad enough, but damn, not allowing another OS see the disc as readable is absolutely INSANE!!!"
