Andre, stop blathering, and answer the question.

The code on both sides of the #ifdef is the same.


Don't bleat about standards and ATA-4/5/6. They won't make the code behave
any other way.

Why do you have a config option that doesn't _do_ anything, except restate
the exact same test in two different ways?

Doing the same test in two different ways and making it _look_ like two
different tests is confusing. Your explanation seems to be that "the
standards are confusing, the source code had better be confusing too". And
quite frankly, that is not a very good reason.
