Summary: info on disk size limits

The ST hard disk format is that same as used on MS-DOS 2.X systems, and has
its same limitations.  In particular that's where 32MB size limit per disk
partition comes from.  The only way to make it bigger would be to increase
the number of sectors per cluster, which may or may not work under GEMDOS.
(And it would depend on whether or not the driver would understand logical
sector numbers that didn't fit in a 16-bit word).

The code to create/delete files in GEMDOS is particularly slow (probably
because of seeking back and forth between the FAT and where the data is
being written much more than it should).  This is the reason for the
recommendation that partitions have a maximum size of around 10MB.
