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/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.

partx - telling the kernel about presence and numbering of on-disk partitions.
SYNOPSIS
partx [-a|-d|-l] [--type TYPE] [--nr M-N] [partition] disk
DESCRIPTION
Given a block device ( disk ) and a partition table type , try to parse the partition table, and list the contents. Optionally add or
remove partitions.
This is not an fdisk - adding and removing partitions is not a change of the disk, but just telling the kernel about presence and numbering
of on-disk partitions.
OPTIONS -a add specified partitions or read disk and add all partitions
-d delete specified or all partitions
-l list partitions. Note that the all numbers are in 512-byte sectors.
--type TYPE
Specify the partition type -- dos, bsd, solaris, unixware or gpt.
--nr M-N
Specify the range of partitions (e.g --nr 2-4).

The partx command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
