Err, because as I replied in a previous message (did you not see it?), it 
was up to the programmer to implement an optimal strategy to access the 
sectors, depending upon the device?  I'm not being snarky, but it seems 
like an obvious choice (if not a hint) to me...

Let's see, I need a strategy to optimise access, taking into account
seek and rotational latency.  I know!  I'll call it XXstrategy()!

For example, I could envisage a disk where the sectors are deliberately 
not numbered sequentially i.e. they've taken rotational latency into 
account for you?

Out of interest, what would you have called it?  XXaccess(), perhaps?
