I was literally listening to mine last night when it crashed. I did a restart (down back or whatever) and it then restarted and got stuck on the loading screen with a full bar just like that. That's... friggin weird.
I guess this is Microsoft's way of punishing us for not going up to the next gen.
Edit : I figured it was just mine that was busted but apparently not.
It's a problem with all 30gb Zune's. Some say being on older firmware prevented the crash, others are saying they are on the older firmware but it crashed anyway. For sure though, If you're zune is on the current firmware it probably crashed.
Doesn't affect any v2 zune's (4,8,80,120) it seems.
Microsoft seems to know that it's an issue :

Status:
Customers with 30gb Zune devices may experience issues when booting their Zune hardware. We?re aware of the problem and are working to correct it. Sorry for the inconvenience, and thanks for your patience!
There is a "fix" where you can remove the battery and basically hard reset the zune - But people are reporting that while this "fixes" it - The next time you connect it to the computer to sync/add songs whatever it'll crash it again.
I'm not too inconvenienced by this - So I'm mainly finding it pretty hilarious that there was a global crash like this. But if they don't find a good fix for it/won't fix replace my zune.. i'll be a sad puppy.
