- .SH DESCRIPTION
- .PP
- When fIfdiskfR 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-2MINIXs+2,
- DOS or other, as well as active or not.
- Using fIfdiskfR is self-explanatory.
- However, be aware that
- repartitioning a disk will cause information on it to be lost.
- Rebooting the system fIimmediatelyfR
- is mandatory after changing partition sizes and parameters.
- s-2MINIXs+2,
- &s-2XENIXs0, s-2PC-IXs0, and s-2MS-DOSs0 all have different
- partition numbering schemes.
- Thus when using multiple systems on the same disk, be careful.
- .PP
- Note that
- s-2MINIXs+2,
- 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-DOSs0 is that s-2MS-DOSs0 allocates disk space in units of
- 512-byte sectors, whereas
- s-2MINIXs+2
- uses 1K blocks.
- fIFdiskfR has a variety of other features that can be seen by typing fIhfR.
- .PP
- .I Fdisk
- normally knows the geometry of the device by asking the driver. You can use
- the fB-hfP and fB-sfP options to override the numbers found.
