HDDs always come manufactured like that. There's never the full 60GB, or whatever is advertised. Check to make sure you aren't filling it up with DLC and XBLA. Demos and videos can really take up some space.
im using my 60gb that came with my pro
but im pretty sure it isnt registering the full 55.8gb or what ever is free on it
i only have about 30gb on it but it has 10gb left
Anyone know what the problem is?
