A regular maintenance avoids the degradation of your equipment

In an hard drive, one finds plates rigid in rotation. Each plate consists of a disc generally made out of aluminium, which has the advantages of being light, easily usinable and nonmagnetic. More recent technologies use glass or the ceramics, which allow surface qualities still better than those of aluminium. The faces of these plates are covered with a magnetic layer, on which the data are stored. These data are written in binary code [0,1] on the disc thanks to a read/write head, small antenna very close to magnetic material. According to the electric flux which crosses this head, it modifies the local magnetic field to write either one 1, or one 0, on the surface of the disc. For reading, it is the same principle which is used, but in the other direction: the local magnetic field generates an electric flux within the head which depends on the value previously written, one can thus read one 1 or one 0.

A typical hard drive contains a central axis around whose the plates turn at a number of constant revolutions. The read/write heads are connected to the same reinforcement which moves on the surface of the plates, with a head by plate. The reinforcement radially moves the heads through the plates while they turn, thus making it possible to reach the totality of their surface.

Associated electronics controls the movement of the reinforcement as well as the rotation of the plates, and carries out the readings and the writings according to the requests emitted by the controller of the disc. The firmwares of the recent hard drives are able to organize the requests so as to minimize the access time to the data, and thus to maximize the performances of the disc.

Why carry out a cleaning disc?

The Nettoyage tool of disc enables you to release from space on your hard drive by seeking on your disc the files which you can remove in full safety.

You can choose to remove certain files or all. Use Nettoyage of disc to carry out the following tasks in order to release from space on your hard drive:
• To remove temporary files Internet.
• To remove the files downloaded programs, for example ActiveX controls and the Java applications which you downloaded on Internet.
• To empty the Basket.
• To remove the temporary Windows files.
• To remove optional the Windows components which you do not use.
• To remove the programs installed which you do not use any more.

Many users do not think of carrying out a cleaning of their hard drive regularly what involves a deceleration of their operating system or its failure.

At the time of an intervention in a customer we found ourselves with U system Windows XP with only 6,6 MO of free space, our customer did not have never to clean her disc, they was necessary for us to intervene in 2 times in order to carry out a complete cleaning of its PC.

The utility cleaning disc lasted more than 3 hours for an hard drive of 40 go and the utility of defragmentation failed 2 times in its procedure. By the continuation it been necessary to repair all the registers and to carry out a complete update of its system and its pilots.
As information, an intervention of maintenance generally proceeds in 1:30.
