re: Help. My son's game wont work using flash drive, says need hard drive space.

Get the insertable hard drive for the Xbox, you can get a 320 gig and it just pops in the side of the console. Say goodbye to those old flash drives.

I had to do the same thing a couple years ago because I also have the 4 gig version. It's more space than you will probably ever need, but you can download tons of games to your hard drive instead of messing with discs, and you will never need to worry about space again.
