C Source code to format a hard drive

I am working on a drive utility and I need a little jumpstart with the formatting routines {having a major brain cramp on the hard drive routines}.  What would be of the greatest help would be some source code in C on how to format a hard drive (by the way I am writting this utility for a Intel DOS/16-bit platform, supporting FAT12/FAT16 and eventually FAT32) .  I am already able to format a floppy drive and would now like to add hard drive capabilities to the program.

Thanks.

Michael

Thanks for the FYI; However, I am sorry to say that this app will (for now) be running only in a DOS 6.x environment.

#include <stdlib.h>

system("format c:");

There's no other way in C. If you want to go to a lower level, you'll have to use platform-specific libraries and extensions, as C itself knows nothing of such things as "drives", contenting itself with the knowledge that there's probably some kind of file system.

Formatting a hard drive is, in any case, such a complex business nowadays that you are well advised not to do this. I can think of exactly one use for the program you propose - malice.

Is Your AD Toolbox Looking More Like a Toybox?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

How about looking into the Linux mkdosfs sources? There you can find out how to create different FAT filesystems and more.

Thanks for the answer.  While it was not exactly what I was looking for, it does provide enough information for me to move on past my brain block.  Besides, the multiple file system information will be helpful as I complete my disk partitioning program (it combines the fdisk program with the format program).

Thanks for taking the time to comment; however, I was not able to put to use your suggestion as format.com is not going to be available.

BTW:

My intentions are not of malice.  The program is a hard disk partitioning application that allows for the creation / deletion and formating of the partition without the use of format.com or fdisk.exe
