Review the definition of the data structure first: Data structure is based on the relationship between the data, including the logical relationship between the data, the storage of data in the computer (storage structure) and the operation of data in three aspects. Everyone in the study of computer knowledge must not rigid thinking, such as data structure, think what tree defines a textbook on the list only ah, ah, ah, is the queue data structure, in fact, fundamentally speaking, who meets the above definition of what is the data structure, and this kind of things can be seen everywhere in the computer for example, here comes the hard disk partition, and FAT table, NTFS table, directory storage and so on are data structures, and some are not standard, such as the hard disk partitioning today talked about is the tree and chain combination, and FAT actually should be similar to the bitmap (? Further research), these are not the standard way, actually dont study so much, here refers to the concept of data structure is drew attention to the logical relationship of hard disk partition used (single tree and table), storage structure (partition table) and operation (the recognition process of the hard disk partition and restart the computer hard disk mode the). Talk less, book the book. First, the physical structure of the hard disk The storage data of hard disk is realized according to the principle of electric and magnetic conversion. The hard disk by one or several head coated with magnetic material such as metal or glass material and a disk installed on both sides of the disc and the corresponding control circuit, wherein the disc head and sealed in a metal shell in the dust. When the hard disk works, the disk rotates at a high speed with the design speed, and the magnetic head arranged on the surface of
