Buy a Memory Unit

I have a similar situation ... I just bought a 360 a few days ago. I was looking forward to downloading the F.E.A.R. Demo ... But now it's not on the Marketplace list! But my friend has the demo on his 360 Hard Drive ... Can we copy that DEMO from his onto mine?

I think that would be possible if we had an extra slot for hard drives.It doesn't seem to be easy to copy those big files into a memory card.However, there are some devices in the market to copy the files from 360 to pc then pc to other 360's hard drive.

Thanks man! Would you be able to list some of those devices please? I really don't want to buy the game before I try it. I've done that in the past and got hosed several times. And of course the local rental store never has this title on hand. I guess this is what happens to the people who wait to buy the newest consoles until later - they have to beg, borrow, and plead. Thanks again!
