HDD Protection Hard Drive - one of the most important components of a computer system, because it is responsible for long-term storage of information.Therefore hard drive protection from mechanical damage and software failures - number one task in maintaining its performance.

Hard drive - very complex electronic-mechanical design.However, considering its structure simplified, we can say that hard disk consists of three main units : magnetic disks, magnetic reading heads and chip control.Failure of one of these units entails a breakdown of a hard drive and as a consequence - loss of data.

The principle of hard disk is as follows.At block disks made of aluminum or ceramic and covered with a thin ferromagnetic layer by a magnetic head to write and read information.

disks mounted on a spindle which is rotated at a high speed, thereby creating an air cushion between the working surface of the disk and the magnetic read / write heads.This protects the disc from theft mechanical contact with the head, because in the

event of impact damage to the surface of the ferromagnetic coating, which may cause data loss in this sector of the hard drive.

To avoid this, you must comply with the basic rules HDD Protection .

Rule one - observe the temperature regime .Too high or too low temperatures can have on your hard drive performance is very big impact, because under the influence of temperature change microgeometrical parameters of the hard disk platters.Although manufacturers of modern hard drives have made every effort to influence this information to zero, nevertheless desirable to exceed the upper limit of the operating temperature of the hard drive, which is 55-60 & amp; degS.

Hard drive - a device with passive cooling, so air circulation is necessary to ensure sufficient clearance between itself and the elements of a hard drive enclosure.This advisable not have hard drives close to each other, next to the graphics card, optical drive, or other elements that actively produce heat .Furthermore, it is desirable that the contact area of ​​the hard drive with metal casing was sufficiently high - it provides heat dissipation to the housing.

resort to the installation of devices for active cooling of the hard drive should be a last resort, very carefully and cautiously approaching the issue.The fact that the vibration of the cooler installed on the hard disk can not be less harmful to the operation of the drive, than the high temperature. With increased vibration time searching for the right track increases increases the load on the hard drive and all of the nodes as a result of life of the hard disk is greatly reduced.

HDD Protection from bumps and jolts - one of the main conditions for the proper handling.Blow to Winchester can lead to a deviation of the head from its position, so that might be the so-called cotton head - to return to the starting position of the head strikes the surface of the disc and damage the ferromagnetic surface.This danger is mainly the hard drive, as in a disabled state, the magnetic head of modern hard drives are parked - automatically displayed outside of the disc surface.

addition to mechanical protection for the hard drive, you must also provide his surge protection .The sharp increase in voltage causes a sharp increase in the temperature of the hard drive components and can lead to overheating of the control circuit.Therefore, care should be taken on the supply of computer system serviceable power supply the required power, as well as uninterruptible power supply, which insure the computer in the event of unexpected power outages.

Unfortunately, even observing all the precautions and protection rules, is not always possible to protect the hard drive from malfunctions.This may be due to the wrong selection, your computer, poor quality parts, too high load on the system.Therefore most reliable way to insure against the loss of valuable data - a data backup to external drives , for example, to other internal or external hard drives, DWD or CD-disks, flash drives.
