硬盘0磁道修复（Hard disk 0 track repair） Hard disk 0 track (zero track) damage repair!

In a total of 512 bytes of hard disk master boot record sector, 446 bytes belong to the hard disk master boot program, and 64 bytes belong to the hard disk partition table (DPT), and two bytes (55 AA) belong to the end of the partition flag.
