Detailed explanation of Hard Disk RAID technologyI. Raid DefinitionRAID (Redundant Array ofindependent disk independent redundant disk array) technology was proposed by the University of California at Berkeley in 1987, initially to combine small cheap disks to replace large expensive disks, at the same time, it is hope
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 MBR
I. Physical Structure of the hard disk:Hard Disk Storage Data is implemented based on the principle of electric and magnetic conversion. The hard disk is composed of one or more metal or glass material disks
First, we need to understand some concepts about how to partition a hard disk. Take a look at the following Glossary:
Physical Disk: a real hard disk is called a "physical disk ". Logical Disk
As we all know, salt is a daily intake of elements, and the main ingredient of salt is sodium chloride, we know in high school chemical name NaCl. But this time we're not talking about the magical use of the table, according to a new discovery published by the Singapore Science and Technology research agency, that sodium chloride can be used to significantly increase the capacity of the hard disk.
Specific
This is due to the improper use of your hard drive bad track (Bad Way test method: in DOS with input command scandisk/all carriage return, disk scan, if one or a number of black bottom of the red word "B" to prove that the hard drive has a bad way, the consequences of Bad way is: Light hard
The hard disk is composed of two parts, the main disk component and the control circuit board in the physical structure. Here is the introduction of the head disk components.
The head plate is the meaning of the head and disk, and the header plate assembly includes t
analysis of the difference between U disk and mobile hard disk
First, the principle of storage is different.
U disk is a semiconductor material (chip) as a storage unit, also known as solid memory, there is no mechanical part. The removable hard
Many computer users have seen or heard that when the so-called "logical lock" is applied to a hard disk, no matter whether it is a floppy disk, hard disk, or a CD, some computers cannot be started. So what is "logical lock?
The so-called "
If 2013 was the first year of smart routing, 2014 would be the first year of its existence. In April 23, 2014, Xiaomi, who entered the routing field with Internet thinking, released two routers in Beijing Zhongguancun Software Park, a high-end vro with a built-in 1 TB hard drive, A vro with no built-in hard disks. Of course, the high-end version of the built-in 1 TB har

The former is soft and bad sectors, which are usually caused by software operations or improper use and can be repaired by software. For example, you can use Scandisk to fi
Hard Disks include SSD, HDD, and HHD. SSD uses flash memory particles for storage, HDD uses magnetic discs for storage, and hybrid hard disks (HHD: hybrid hard disk) is a hard disk that integrates the magnetic
Partition Table faults
After the partition table is damaged, "non-system disk or disk error, replace disk and press a key to reboot" (non-system disk or disk error) often occurs when the system is started) "error loading operating system" (loading dos Boot Record error) or
The writing of the data is actually on the platter, the disk can be divided into the sector and the cylinder two units, of which the sector each 512bytes so large.
The first sector of the disk mainly records two important information, respectively:
Primary boot Sector (MBR): Where the boot loader can be installed, 446bytes;
Partition table: Records the status of
1. HeadThe head is a key component of the hard disk to read data. Its main function is to convert the magnetic information stored on the disk to an electrical signal for external transmission, the working principle is that the resistance value of special materials changes with the magnetic field to read and write data on the
Everyone must have had a bad experience of data loss. The data collected with full effort should be destroyed due to virus damage, accidental deletion, formatting, misoperations of partition software, storage device damage, and other reasons, it is really sad. In fact, we only need to calm down and learn a little bit about data recovery. In this unfortunate situation, if it is not a serious hardware damage, we can recover some of the data. If we're lucky, it is also possible to retrieve all the
1. The system does not recognize hard disks.This type of fault is common, that is, the disk cannot be started from the hard disk, and the disk cannot be started from disk a to drive C. The existence of the
