硬盘分区表知识——详解硬盘MBR(国外英文资料) The hard disk is one of the most popular memories on the computer now. We all know that computers are amazing because they have the ability to analyze and process data at a high speed. These data are stored as files in the hard disk. But computers are not as smart as people. When you read the corresponding file, you must give the corresponding rules. This is the partitioning concept. Partitioning is essentially a format for a hard disk. When we create partitions, we have set up the physical parameters of the hard disk, specifying the hard disk master boot record (Master, Boot, Record, generally referred to as MBR) and the storage location that guides the record backup. For the file system and other operating systems, the information needed to manage the hard disk is achieved by later high-level formatting, or Format command. After partitioning the face, track, and sector drives, they will be divided into Side, Track and Sector. Its important to note that these are just virtual concepts, not real tracks on your hard disk. First from the surface, the hard disk is usually made of one or more pieces of circular film. We say that every round film has two faces, and these two surfaces are used to store data. In accordance with the number of planes, in turn called 0, 1, 2...... Since each surface has one read-write head, 0 heads (head) and 1 heads are also used...... Call it. In accordance with the capacity and specifications of hard disk drive, the number of hard disk (or head) is not necessarily the same, less only 2 sides, more than dozens of surface. The tracks with the same number of tracks on each face are called a cylinder (Cylinder). We mentioned the concept of tracks above. So what exactly is the track? Since the disk is rotated, the data that is written continuously is arranged on a circle. We call such a circle a track. If the read-write head moves along a radius of the circular film, the data later written is arranged on another track.
