FDISK(8)FDISK(8)NAMEfdisk - partition a hard disk [IBM]
SYNOPSISfdisk [-hm] [-sn] [file]
OPTIONS-h # Number of disk heads is m
-s # Number of sectors per track is n
EXAMPLESfdisk /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 number‐
ing 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.
