mystery of the missing 30 Gigs...

Can anyone tell me why my 500 GB Seagate Barracuda 7200.10 scratch drive with nothing on it reads as only 465.8 GB in my Macbook Pro's disk utility information? It's in an icy dock enclosure and connected to my mac by an esata express card if that matters.

a 500gb hard drive can store 500,000 bits of information. a gb is actually 1,024,000. its a marketing strategy

This is an old marketing trick of the drive manufacturers. They're advertising and selling their drives by defining 1 GB as 1 billion bytes. However, for a computer 1 GB = 1,073,741,824 bytes (1024 x 1024 x 1024).

Divide 500,000,000,000 by 1024 three times and you'll end up with 465.

As I said, old marketing trick. Or call it a a question of definitions.
Best,
Dino

LOL! I also had to think twice about how many zeros.... it's crazy if you think about the amount of data we keep wasting...
