FDISK

Starts the Fdisk program, which configures a hard disk for use 
with MS-DOS.

Fdisk displays a series of menus to help you partition your hard 
disk(s) for MS-DOS.

Note: Fdisk has a command format not delared by Microsoft. 
The command format is: "FDISK /MBR". Use this command to rewrite 
the Master Boot Record with a standard hard disk boot program. 
This may affect some multiple OS startup programs. This doesn't 
affect existing partitions.

FDISK changes boot sectors of created partitions, so if 
partition table information is lost, you should not use FDISK if 
you still want the data. You can try using Norton Disk Doctor 
(NDD.EXE) for MS-DOS included in Norton Utilities 4.0 or higher 
for Windows 9x to find the lost partition information back.

If you want to format created partitions, be sure to restart 
your computer before doing that. Or, newly created partitions 
will not be recognized by FORMAT.

For more information, please refer to MS-DOS Help or Windows NT 
command line command help.
