Close does not count.

Seagate, makers of hard drives for computers, have been caught lying. They say that a gigabyte equals a billion bytes of storage.

On a 1GB drive, this would make the difference between one billion bytes of storage, and 1,073,741,824 bytes. Other manufacturers, such as Samsung and Hitachi, also measure hard-drive capacity with 1KB equalling 1,000 bytes, whereas all operating systems are based on 1KB equalling 1,024 bytes.

But they're wrong, and they'll pay you money if you bought a product from them. You'd think that computer hardware manufacturers could get this right. Use your words, and know what they mean.
