First, FAT12 FAT12 is the file system that started using the DOS era, and is still used on floppy disks, and the FAT12 floppy disk is formatted with two heads, 80 cylinders per head (track), 18 sectors per cylinder, and 512 byte space per sector. So the total space for the standard floppy disk is: 2 * *18 * 512=1474560b=1440k=1.44m The following is a diagram of the FAT12 structure: 1. Boot Sector The secret

represents a group of 512 bytes. Therefore, Sector 1 represents the first 512 bytes of a disk. Fan Surface A "fan" (or a fan) represents one side of the disk. Fan 0 indicates the front side and FAN 1 indicates the back side. Most disks have only one side, so there is only one fan ("fan 0 "). Track To understand the track, let's look at the following figure: In this figure, the disk can represent a hard di

I. fat12 Fat12 is a file system used in the DOS era. It is still used on a floppy disk until now. After the fat12 floppy disk is formatted, it has two heads, each head has 80 cylinder (track), each cylinder has 18 sectors, and each sector has 512 bytes of space. Therefore, the total space of the standard floppy disk is: 2*80*18*512 = 1474560b = 1440 K = 1.44 m The structure of fat12 is as follows: 1. Boot S

The extended partition can be divided into several partitions, each of which is a logical partition. MBR, extended partitions, and logical partitions One is the information area for storing the hard disk, which is called the master boot recorder (MBR) and the other is the place where the actual file data is stored. MBR is the most important area of t

C is always at the top of all disk partitions.The MBR (primary Boot Record) Partition Table (primary Partition Table) can only store four partitions. To divide more partitions, an extended partition table (EBR) is required ), the extended partition table is placed on a primary partition with the System ID 0x05. The primary partition is an extended partition. The extended partition can be divided into several partitions, each of which is a logical partition. MBR, extended partitions, and l
