There is a problem with this: someday The Powers That Be may come up with a
file system for the Amiga that tries to optimize disk layout and disk block
allocation. (A simple optimization is avoiding track to track seeks wherever
possible.) If this happens, you would get the best performance out of your
drive by *not* lying to the file system.

The moral? DON'T lie to the system unless you have to. (I seem to remember
that the 2090 does not like >63 sectors/track or something like that, in
which case you *do* have to lie.)
