FDISK(8)                    System Manager's Manual                   FDISK(8)

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/c0d0     # Examine disk partitions

       fdisk -h9 /dev/c0d0 # 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 3, 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  system
       immediately is mandatory after changing partition sizes and parameters.
       MINIX  3,  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 3, 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 3 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.
