Looks like that particular demo song is damaged, bigy. See the Troubleshooting section of the User's Guide...

Hi Dave. I'm finally joining you in the Mac World & loving it. I'm developing an iPhone app.

Overnight I ran SuperDuper on my MacBook Pro & got a similar message on a Garageband guitar lesson file. The target is on an NTFS drive on a Windows XP Pro system. It got about 60gb into it before running into the error.

Coincidentally, I was planning on installing a Garageband update after SuperDuper completed. But now I'll try some recommendations from the Troubleshooting section of the User Guide.

Is this a common problem, i.e. bad Garageband files?

Dave

I think Garageband files show up a bit more often because they're large and pretty static - that is, they were part of the preinstall and haven't been updated since the laptop was purchased.
