Okay time to get a clue...

1 byte = 8 bits ( 2^0 )
1 kilobyte = 1024 bytes (can we say 2^10 )

>1 megabyte = 1 million bytes
1 megabyte = 1024 kilo bytes (can we say 2^20 )

>1 gigabyte = 1 billion bytes
1 gigabyte = 1024 mega bytes ( 2^40 )

>1 billion = 1000 million
true however in computerese it is more like:
1 giga = 1024 mega

actually 2,147,483,648 bytes so you are off by 147,483,648 or about
140.65 Megabytes

Of course in the case of a hard drive  this is mute since it is before 
formatting so you only et about 1.5 - 1.8 Gigs a storage. Funny how salepeople
never mention that fact.
