| 23 | .SH DESCRIPTION
|
|---|
| 24 | .PP
|
|---|
| 25 | When \fIfdisk\fR starts up, it reads in the partition table and displays
|
|---|
| 26 | it.
|
|---|
| 27 | It then presents a menu to allow the user to modify partitions, store the
|
|---|
| 28 | partition table on a file, or load it from a file. Partitions can be marked
|
|---|
| 29 | as
|
|---|
| 30 | \s-1MINIX 3\s-1,
|
|---|
| 31 | DOS or other, as well as active or not.
|
|---|
| 32 | Using \fIfdisk\fR is self-explanatory.
|
|---|
| 33 | However, be aware that
|
|---|
| 34 | repartitioning a disk will cause information on it to be lost.
|
|---|
| 35 | Rebooting the system \fIimmediately\fR
|
|---|
| 36 | is mandatory after changing partition sizes and parameters.
|
|---|
| 37 | \s-1MINIX 3\s-1,
|
|---|
| 38 | \&\s-2XENIX\s0, \s-2PC-IX\s0, and \s-2MS-DOS\s0 all have different
|
|---|
| 39 | partition numbering schemes.
|
|---|
| 40 | Thus when using multiple systems on the same disk, be careful.
|
|---|
| 41 | .PP
|
|---|
| 42 | Note that
|
|---|
| 43 | \s-1MINIX 3\s-1,
|
|---|
| 44 | unlike
|
|---|
| 45 | \&MS-DOS ,
|
|---|
| 46 | cannot access the last sector in a partition with an odd number of sectors.
|
|---|
| 47 | The reason that odd partition sizes do not cause a problem with
|
|---|
| 48 | \s-2MS-DOS\s0 is that \s-2MS-DOS\s0 allocates disk space in units of
|
|---|
| 49 | 512-byte sectors, whereas
|
|---|
| 50 | \s-1MINIX 3\s-1
|
|---|
| 51 | uses 1K blocks.
|
|---|
| 52 | \fIFdisk\fR has a variety of other features that can be seen by typing \fIh\fR.
|
|---|
| 53 | .PP
|
|---|
| 54 | .I Fdisk
|
|---|
| 55 | normally knows the geometry of the device by asking the driver. You can use
|
|---|
| 56 | the \fB\-h\fP and \fB\-s\fP options to override the numbers found.
