It must be a virus or a big screw up on the firmware. I, too, have the exact same problem. I got my Zune 30 Factory Refurb since Oct 2007. It locked up once in a while but this is the first time it doesn't respond to any command. Same situation as everybody here, this morning, out of the blue, the Zune booted up and froze on the logo screen. I can hear the harddisk spining. The progress bar is full. The screen lit up.
