If my performance depends on my kernel knowing how my drive is laid out, I would always be wondering if a new drive is going to break any of the kernel's geometry assumptions. Drive geometry doesn't seem like a kernel's business any more than a kernel should be able to decode the ccd signal of an optical mouse. The kernel should queue requests at a level of abstraction that doesn't depend on intimate knowledge of drive geometry, and the drive should queue requests on the concrete level where geometry matters. A drive shouldn't guess whether a process is trying to read a file sequentially, and a kernel shouldn't guess whether sector 30 is contiguous with sector 31 or not. __ David B.
