Hi I have just purchased what I though was a 20GB xbox hard drive, for some reason its only showing as 13GB. I though there was only 20, 60 & 120's available.
You can buy a 80GB iPod but only be able to use 76GB of it. You have to allow room for the firmware, the operating files, drivers, ect. Same thing with the 360 HDD, you have to allow room for the required files. This goes for every type of storage device, even flash drives. I have a 4GB flash drive that only has 3.8GB of storage.

Binary numbers are numbers that are a power of 2.
Decimal numbers are numbers that are a power of 10.
2^10 is 1,024 the closest Decimal number is 10^3 or 1,000
2^20 is 1,048,576 The closest Decimal number is 10^6 or 1,000,000
2^30 is 1,073,741,824 The closest Decimal number is 10^9 or 1,000,000,000

I understand that but do you not think that 7GB if slightly high? I had a 256 mem card prior to this and 128 was taken for system files.

Kinda understand this, I work for a ISP and they class 1000 MB as a GB
. Im still thinking that losing nearly 7 gig isnt right.
On a side note, I'm thinking of upgrading to 120GB with one of These, Would I be able to convert the 20GB drive to PC format and sell it to offset the cost?
Back in the day when 20 GB was premium, you only had 13.7 GB on a brand new one because they put stupid demos, videos and themes on the HDD. Format it and you'll get "most" of it back.
