cfdisk [-agvz] [-c cylinders] [-h heads] [-s sectors-per-track]
[-P cfdisk is a curses/slang based program for partitioning any
hard disk drive. Typical values of the device argument are: In
order to write the partition table cfdisk needs something called
the `geometry' of the disk: the number of `heads' and the number
of `sec- tors per track'. Linux does not use any geometry, so if
the disk will not be accessed by other operating systems, you
can safely accept the defaults that cfdisk chooses for you. The
geometry used by cfdisk is found as follows. First the partition
table is examined, to see what geometry was used by the previous
program that changed it. If the par- tition table is empty, or
contains garbage, or does not point at a con- sistent geometry,
the kernel is asked for advice. If nothing works 255 heads and
63 sectors/track is assumed. The geometry can be overridden on
the command line or by use of the `g' command. When partitioning
an empty large modern disk, picking 255 heads and 63 sectors/tra
