It's not clear that "ordinary users" ever have this problem. It seems to happen 
*only* when using a drive which has something which looks like a partition table 
but isn't, or is a defective partition table, or will only work when diddling 
with HPA magic.

And should some naive user be trying to use such a drive, it seems better to 
tell them, to beat them over the head with the problem, because if you hide the 
problem those users are least likely to be able to recover when problems arise.

I'm not against some sensible recovery, I just don't agree that "pretend it 
isn't wrong" is a good default solution.
