Write to a disk in the A drive

Posted on February 14th, 2009 in C by admin

This requires an older operating system and compiler, Turbo C and Windows 98 for example

#include <stdio.h>
#include <dos.h>
#include <stdlib.h>
#include <bios.h>

int main(void)

{
unsigned char buffer[512];
clrscr();
printf(”Insert a blank disk in the A: drive , then press any key.\n”);
/*wait for keypress*
getch();
if(abswrite(0,1,1,&buffer) != 0)
printf(”Cannot write to the A drive.\n”);
else
printf(”Drive A , Sector 1 written to\n”);
return 0;

}
