Whats the point of a bigger HDD if you cant use it?

[Garnett]

So i got the red 360 Elite,120 gig HDD and all.

 

I had like 30 gigs left and i had CoD Map pack 1 and 2 downloaded already.

 

So i install another game and then i go to play WaW and it says i dont have map pack 1 but 2 works fine.

 

I clear some useless games and i have 60 gigs now and i redownloaded it and now it works fine.

 

Whats the point?
