There's no data on it, and I don't care about the disk particularly. If I really need it at some point, I've got a dual boot windows PC in the lounge room that serves as a media PC for the family that I can use to unlock it.

I bring it up mostly because it's indicative of the hardware pain points. It's also typical of them in that it's annoying, relatively minor, and generally the fault of proprietary locking down, rather than a true compatibility issue.
