.SH DESCRIPTION
|
|
.PP
|
|
When \fIfdisk\fR 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
|
|
\s-1MINIX 3\s-1,
|
|
DOS or other, as well as active or not.
|
|
Using \fIfdisk\fR is self-explanatory.
|
|
However, be aware that
|
|
repartitioning a disk will cause information on it to be lost.
|
|
Rebooting the system \fIimmediately\fR
|
|
is mandatory after changing partition sizes and parameters.
|
|
\s-1MINIX 3\s-1,
|
|
\&\s-2XENIX\s0, \s-2PC-IX\s0, and \s-2MS-DOS\s0 all have different
|
|
partition numbering schemes.
|
|
Thus when using multiple systems on the same disk, be careful.
|
|
.PP
|
|
Note that
|
|
\s-1MINIX 3\s-1,
|
|
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
|
|
\s-2MS-DOS\s0 is that \s-2MS-DOS\s0 allocates disk space in units of
|
|
512-byte sectors, whereas
|
|
\s-1MINIX 3\s-1
|
|
uses 1K blocks.
|
|
\fIFdisk\fR has a variety of other features that can be seen by typing \fIh\fR.
|
|
.PP
|
|
.I Fdisk
|
|
normally knows the geometry of the device by asking the driver. You can use
|
|
the \fB\-h\fP and \fB\-s\fP options to override the numbers found.
