Sounds normal to me.

The actual formatted capacity of a 640 gig drive is about 596 gigs.

Formatted capacity is about 7% less than advertised capacity.

The numbers the system shows are in binary. The number the sticker shows is in decimal. And at the GB level, the difference (in numbers) is about 7%. But 93GB in binary are still 100 billion bytes.

You are right, now multiply 1024x1024x1024 to get to GBs, and you will see that it is 7% more in value. So 100GBs in binary would be 107GB in decimal.

It's because you have to live with less if you are a nerd and live in the base 2 world. Those base 10 bullies just kick their excess bits in your face. Ouch!
