Lire un secteur d'un disque.

J'ai deux structures:

Code:

1
2
3
4
5
6
7
8
9
10
11
12
13
//----------------------------------------
struct diskfree_t {
unsigned total_clusters;
unsigned avail_clusters;
unsigned sectors_per_cluster;
unsigned bytes_per_sector;
};
//----------------------------------------
struct diskinfo_t {
unsigned drive, head, track, sector, nsectors;
void far *buffer;
};
//----------------------------------------

Mais je ne sais pas comment faire.
