NAME

       fdisk - partition a hard disk [IBM]

SYNOPSIS

       fdisk [-hm] [-sn] [file]

OPTIONS

       -h     Number of disk heads is m

       -s     Number of sectors per track is n

EXAMPLES

       fdisk /dev/hd0	   # Examine disk partitions

       fdisk -h9 /dev/hd0  # Examine disk with 9 heads

DESCRIPTION

       When  fdisk  starts  up,  it reads in the partition table and displays it.  It then presents a menu to allow the user to modify partitions,
       store the partition table on a file, or load it from a file.  Partitions can be marked as MINIX, DOS or other, as well as  active  or  not.
       Using fdisk is self-explanatory.  However, be aware that repartitioning a disk will cause information on it to be lost.	Rebooting the sys-
       tem immediately is mandatory after changing partition sizes and parameters.  MINIX, XENIX, PC-IX, and MS-DOS all have  different  partition
       numbering schemes.  Thus when using multiple systems on the same disk, be careful.

       Note that MINIX, unlike MS-DOS , cannot access the last sector in a partition with an odd number of sectors.  The reason that odd partition
       sizes do not cause a problem with MS-DOS is that MS-DOS allocates disk space in units of 512-byte sectors, whereas MINIX  uses  1K  blocks.
       Fdisk has a variety of other features that can be seen by typing h.

       Fdisk normally knows the geometry of the device by asking the driver.  You can use the -h and -s options to override the numbers found.
