在实际使用的数据恢复联盟
现在让我们看看实际利用联盟数据恢复编程.让我们以一个小例子.以下是节目的小模型界坏了软磁盘驱动器扫描程序(一: )不过这并不是完全扫描软体界不良示范.
让我们研究计画:
#include<dos.h>
#include<conio.h>
int main()
{
int rp, head, track, sector, status;
char *buf;
union REGS in, out;
struct SREGS s;
clrscr();
/* 复位磁盘系统初始化到磁盘 */
printf("\n Resetting the disk system....");
for(rp=0;rp<=2;rp++)
{
in.h.ah = 0;
in.h.dl = 0x00;
int86(0x13,&in,&out);
}
printf("\n\n\n Now Testing the Disk for Bad Sectors....");
/* scan for bad sectors */
for(track=0;track<=79;track++)
{
for(head=0;head<=1;head++)
{
for(sector=1;sector<=18;sector++)
{
in.h.ah = 0x04;
in.h.al = 1;
in.h.dl = 0x00;
in.h.ch = track;
in.h.dh = head;
in.h.cl = sector;
in.x.bx = FP_OFF(buf);
s.es = FP_SEG(buf);
int86x(0x13,&in,&out,&s);
if(out.x.cflag)
{
status=out.h.ah;
printf("\n track:%d Head:%d Sector:%d Status ==0x%X",track,head,sector,status);
}
}
}
}
printf("\n\n\nDone");
return 0;
}
现在让我们看看它的产量将会有什么样的坏软盘部门:

可能有点难以理解功能和使用这一计划中断核查磁盘坏道重新为磁盘系统等,但你不必担心,我们要学习这些东西在稍后的BIOS及中断编程节即将在下一章节.
