OK, thanks for that.

Interesting...

I started using the formula in:

   http://en.wikipedia.org/wiki/Logical_Block_Addressing#CHS_conversion

instead of just guessing how it works.

Also there were attempts to increase the max size, followed by setting
the max size based on the actual size.  Most of these changes have
mostly worked, but not for someone.

For the disk header I use: http://sourceforge.net/projects/garmin-img/
The header is the first thing written so there is no need to let it
run to completion on a large file, nor worry if it crashes after
writing the *DSKIMG* file out.  I use a patched version (patch attached 
against 1.1).

For almost everything else there is a program in 
http://svn.mkgmap.org.uk/display/trunk/ that will print the sections.
