The logic of how to fix hard disk bad sectors?

Logical bad sectors can be said is a soft bad sectors, the disk using the Windows tool can easily be repaired. Specific method is: Go to “My Computer” window, right-click the disk partition bad sectors appear the icon, click the “Properties” menu item, open the disk drive’s “Properties” dialog box, switch to the “Tools” tab , click the “troubleshooting” combo box “Start Error-checking” button that appears “Error-checking disk” dialog box, select “Scan for and attempt recovery of bad sectors” check box, then click “OK” button can. Under Error-checking process 02) How Read More…

01) defragmenting the hard disk “failure”

Recently the use of Windows native defrag functions encounter a strange question, select the. Set by “analysis” button, it says “need to Defrag the hard disk” and then click the “order”, too – after the prompt “order complete”, but distribution of data on the hard disk does not happen any | any change (still very messy ), I cup defrag simply no doubt play a role, how is this going on, hard drive broken? Are there any other way to solve Read More…

Computer operating system is running the most basic, most central and most important software programs control and manage computer hardware (CPU, hardware, keyboard, mouse, graphics etc), software resource (a variety of applications and data files ). There is now more common operating system Microsoft (Microsoft) Windows family, Apple’s MAC series, there is a more common open-source system Linux. Including Microsoft’s Windows family of basic accounting for 90% of the market share, while Windows is Read More…

Introduced in front of computer failure is divided into two categories, namely, “hard failure” and “soft failure” to learn the “hard failure” of the basic diagnosis and treatment, the next will learn “soft failure” of the basic diagnostic and treatment .

Software failure occurs, mainly due to software errors, improper operation of the user, system configuration errors caused by incorrect parameters. Software failure mainly in the software installation, commissioning, operation, maintenance failure, failure generally affect the use of a single software, can lead to serious crashes, the majority of software failures can all be repaired, generally Read More…

You must often hear people say: this computer unstable, often crashes! Stability and instability of a computer, motherboard significant, this and a person’s body is not good, the cold is often the same reason. When you open the shell of the host computer, you will see a board studded with a variety of small circuit board, this piece of board is the motherboard. It is not only responsible for all data communication within the computer, Read More…

Cadmium – nickel battery charging process, with the charge to the battery voltage increases, when the voltage exceeds 1.55V, the electrolyte water electrolysis, precipitation of gas, reduce the charging efficiency, charging efficiency of 85 normal % of. Cadmium – nickel battery charge voltage and charging mechanisms. The greater the charge current, charge voltage higher charge temperature is Read More…

For the secondary battery (batteries, rechargeable batteries) is concerned, life cycle or life cycle is also a measure of battery performance of an important parameter. After a secondary battery charge and discharge, as a cycle, or call a cycle.

Certain discharge conditions, the battery capacity dropped to a specified value before the number of cycles the battery can Read More…

1, according to the different structure can be divided into the following categories.

(1) homojunction solar cell from the same material composition of one or more semiconductor pn junction solar cell. Such as silicon solar cells, gallium arsenide solar cells and so on. Read More…

Solar photovoltaic solar cells is the basis and core of a photovoltaic effect using the optical device can change the energy, also known as photovoltaic devices. With the appropriate wavelength of light shines on some of the material, its absorption of light energy generated at both ends after the electromotive force, known as the photovoltaic effect. This phenomenon in the liquid and solid Read More…

The battery used in tandem or in series constitute a single cell battery use, according to Faraday’s law, a single unit of time per battery and each electrode is equal to the electricity passed, if the capacity difference between the individual cells, or a single cell in the electrode capacity and other single cell capacity of different electrodes, Read More…
