Bad maths

I found an annoying example of bad maths in this BBC story about future Hard Drive issues for Windows XP users, where they stated:

“Each 512 byte sector has a marker showing where it begins and an area dedicated to storing error correction codes. In addition a tiny gap has to be left between each sector. In large drives this wasted space where data cannot be stored can take up a significant proportion of the drive.”

Now, as the sectors are a set size, and the gap is a set size, then the proportion of the drive wasted is the same regardless of whether the drive is 1GB or 500GB. I think what he meant was it could take up a significant amount of data storage space.

Pedantic? Maybe, but I am correct.
