Ha, a discussion about partitions and disk geometry.

It is almost twenty years ago that disks stopped having a geometry.
The ATA standard tells disks over 8 GB to report their geometry as
16383/16/63. That is, there is no information in what is reported.
It is just a constant to satisfy ancient software.
