Probleme d'acces au disque dur (avec code source)

Salut a tous , j'ai un petit probleme avec le code suivant car il ne m'affiche pas les résultats escomptés.

#include <stdio.h> #include <stdlib.h> #include <fcntl.h> #include <assert.h> #include <windows.h> #include <winioctl.h> #define int8 unsigned char #define int16 unsigned short int #define int32 unsigned int int main(int argc,char **argv) { char *chemin="\\\\.\\F:\\"; printf("Lecture de %s\n",chemin); /* HANDLE file; file = CreateFile(chemin,0,FILE_SHARE_READ,0,OPEN_EXISTING,0,0); if(file == INVALID_HANDLE_VALUE) { */ int file; if((file = open(chemin,O_RDONLY)) == -1) { printf("[!] ERROR: can't open [!]"); exit(0); } else { printf("Lecture de la FAT ...\n"); int16 bytes_per_sector; int8 sectors_per_cluster; int16 n_reserved_sectors; int8 n_fats; int32 sectors_per_fat; int32 root_cluster; int16 signature; #define LIREA(file,offset,item) { lseek(file, offset, SEEK_SET); read(file,&item,sizeof(item)); } LIREA(file,0x0B,bytes_per_sector); LIREA(file,0x0D,sectors_per_cluster); LIREA(file,0x0E,n_reserved_sectors); LIREA(file,0x10,n_fats); LIREA(file,0x24,sectors_per_fat); LIREA(file,0x2C,root_cluster); LIREA(file,0x1FE,signature); int32 fat_begin_lba = n_reserved_sectors; int32 cluster_begin_lba = n_reserved_sectors + ( n_fats * sectors_per_fat); printf("Volume identification information\n"); printf("> bytes per sector: %u\t(512 expected)\n",bytes_per_sector); printf("> sectors per cluster: %u\t(power of two)\n",sectors_per_cluster); printf("> reserved sectors: %u\t(usually 0x20)\n",n_reserved_sectors); printf("> file allocation tables: %u\t(should be 2)\n",n_fats); printf("> root cluster: %u\t(usually 2)\n",root_cluster); printf("> signature: %04x \t(should be aa55)\n\n",signature); } return 0; }

Est ce quelqu'un peut m'aider ?
Merci d'avance !

Avec le handle de CreateFile(...):
SetFilePointer(...);
ReadFile(...);
WriteFile(...);
lseek, read etc... rien a y faire.
BruNews, ciao...
