This makes no sense

The great big huge 1.5 TB drive I bought for Corey is a WD15EARS. One thing all those letters mean is that it's an Advanced Format drive. Which is Western Digital Marketing Speak for "we use the new, modern 4k sector size." But of course the drive reports its block as 512 bytes, because otherwise it would fail under Windows. So hoops must be jumped through.

And some of them make no sense.
