Downloading to Hard Drive

So when you download to the Xbox 360 hard drive can you run the game without the disk, or do you still need the disk and it just makes the game run smoother?Downloading to Hard Drive
if you mean installing a game to the hard drive,then yes you still need the game in the xbox tray..installing a game stops the disk spinning when playing it so the xbox runs smoother and more quieterDownloading to Hard Drive
Yes you do need the disk, would hurt sales a lot if you didn't. x:
If by downloading a game you mean Games On Demand, then no. Its a digital game the same as if you has downloaded an XBLA title. If you mean installing it, then I think this answer pretty much sums it up:

I'm pretty sure that he means installing a game to your HDD from the disc. Of course you need the disc in the tray as a way to verify that you in fact own the game. You can't install the game to your HDD and 10 of your friends' HDD's from one disc. They aren't that naive.
I figured you needed the disc in, just wanted to make sure.
