Hi Tom,

Here's the explanation for a 160GB, same logic applies to all sizes:

"A true Gigabyte is actual 1024x1024x1024 bytes.  But the whole computer
industry rounds this to 1000x1000x1000 for ease of understanding.  So when
the manufacturers make a 160GB drive it is actually 160,000,000,000 bytes
whereas the computer will see it correctly as 160,000,000,000 divided by
(1024x1024x1024) = 149.01GB."

Kind regards,
