DOS management structure of hard disk 1. Track, sector, cylinder and head number The most basic component of hard disk is a platter coated with magnetic media made of hard metal materials, and the number of platters of different

the difference between SSD and common hard disk In fact SSD solid-state drives are solid-state storage, belong to flash memory, long service life, not easy to damage, strong earthquake resistance. The disadvantage is: The price is expensive, the capacity is small. Ordinary hard drive inside a platter, work through hi

installation techniques in this column. If you are using the best solution, you have already tried it. However, many netizens and readers have encountered the following typical problems during the dual-disk installation process. Here we will introduce some corresponding solutions. Dual-hard disk drive-character staggered solution After the dual

First, the hard diskThe function of a hard disk is quite simple but important, and it is responsible for recording the various data required by the system. The hard disk record data has two aspects, one is the hardware aspect storage principle and the structure, on the other

structure of the hard driveThe internal structure of the hard disk usually refers to the internal structure of the disc. The disk body is a sealed cavity, which is sealed with the head, disc (magnetic disc, disc) and other components, shown in 1-4.Figure 1-4 Internal Drive structureHard

RAID 1 can help you solve the problem. RAID 1 requires at least two

The disc of the hard disk is made from the surface of the disc that attaches the magnetic powder to the aluminum alloy (the new material also has to use glass), which is divided into concentric circles called "tracks". On each concentric track there is an infinite number of tiny magnets that represent the 0 and 1 states respectively. When these small magnets are affected by the magnetic force from the head,

can be used for USB disk, CD-ROM and other data recovery. Basic knowledge-hard disk, zoning and file system introduction Hard drive internal structure About the hard disk structure of the article has been very much, but really

The composition of a hard disk Hard disk We will not be unfamiliar, we can compare it to our computer to store data and information in a large warehouse. Generally speaking, no matter which kind of hard disk, it is composed of se

Hard Disk repair mistakes, defects, parameters, and low Space Author: Gao Peng Jump out of hard drive misunderstanding In 1995, I accidentally saw a strange object from my colleague and curiously asked what it was. My friend replied, "this is a hard drive for a computer !" This is the first time that Gao Peng knows ab

compressed volume file is increasing, this method has a very obvious disadvantage, that is the hard disk read and write data greatly slowed down. With the rapid development of hard disk technology, the capacity of the disk is also climbing, the current market of

How the hard drive works After the hard drive power is working properly, the initialization of a stand-alone module in the control circuit is performed, at which point the head is placed at the center of the disc, the spindle motor is started a

hard drive, and it is not visible that there is anything in it, only some platters. assuming that you enlarge the disc with a microscope, you will see the uneven surface of the platter, the convex place is magnetized, the concave place is not magnetized, the raised place represents the number 1 (magnetization is 1), the concave place represents the number 0. Therefore, the

1. Tracks, cylinders and sectors The structure of the hard disk disc group is shown in Figure 1. The track (Track) is a concentric 阏 trajectory formed when the head of the hard disk 屮 reads and writes data on the disc surface. The track of the hard

cache algorithm. Thus, because the cache capacity is far less than the main memory capacity, and the cache algorithm can not 100% accurate hit. The role of caching in mechanical hard drives: The above is an example of CPU caching. But in computer systems, caching is not just CPU-specific, because the contradiction between high-speed devices and low-speed devices is not just between the CPU and the memory. Now, if I were to write data from memory to

The next version of the Ext2 file system with log support is the Ext3 file system, which is the same as the Ext2 file system on the hard disk layout, and the only difference is that the ext3 f

Mobile hard disk learning, how to use a good mobile hard drive to ensure the security of data transfer and storage, has become a more topical topic. In order to relieve everyone's worries, small series on this topic carefully for the reader friend to do a little explanation, in order to be able to provide more practica
