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

Well it doesn't "reserve", well maybe it does but what I'm trying to explain is the 1000 vs 1024 bits battle.

So your 120GB HDD is more like 112GiB(This is before inserting it to your Xbox where it does(n't) reserve some of the HDD)

lol, they wouldn't use the term 120 GB if it didn't have that much space.  The 360 reserves about 7 gigs like Twestern said for the os and other system functions.  However, if you clear all the information off the drive, even the os, it would be a full 120 gigs.
