Hard disk maintenance

One of the basics on which the computer is built today is the presence of four main parts in it: the motherboard, the central processing unit, the random access memory and the hard disk, and these four parts the computer cannot work without at all as it needs it to start its operations and to enable the user to enter it and deal with it and with the system in which it works. The focus of this article is on the hard disk, or the so-called hard disk, which is the permanent memory contained in the computer, where all data on the computer is stored on that disk, which enables the user to store his data on it and also the ability to modify it inside the disk and deal with it, and it is considered the center of information and data where it is placed The operating system that connects the physical and intangible components of the computer on it, and is also the source of storing applications, files and information, as it is not possible in any way to keep data without returning to it and without its presence in the computer.

Some times pass on the hard drive and it may crash, and this is considered a major disaster, especially for those who do not have backup copies of the information they have, which leads them to loss and loss of information that may be very important and very important in their lives and greatly affects their lives and job opportunities, especially if it is for a company or For a researcher, or even files of memories that cannot be recovered, or works that have been worked on for a long time, and it is impossible to accept their loss just because of a simple failure in that disk.

Therefore, all those who face malfunctions in their hard disks resort to urgent and immediate maintenance, but the matter is not that easy as many believe, as the hard disk, if what was broken in it, is some external electrical circuits that are easily replaced with circuits of the same type for the hard disk and then It returns to work, but if the main problem is in the internal reader of the hard drive or even the drive that drives the internal disks, then here appears a problem that may not be easy to maintain and repair; The reason for this is that the hard disk cannot be opened without damaging it. The reader is a very small needle. One grain of sand or one grain of dust can stop its work, scratch the disks and destroy the information on those disks. If the user encounters a problem with the needle or Even the motor that rotates the discs must work to provide a sterile room at a rate that exceeds the rate that sterilizes surgical operations for humans, and very sensitive tools and microscopes must be available to be able to change the needle or the motor in the middle, so the process of maintaining this problem is considered a more specialized process Including a literal or manual process, and often hard disk manufacturing companies allow our customers to send the hard disk for repair and maintenance so that they can recover data, but the price provided for that service is rather large, so it is very expensive and depends on the importance of the information that is on the disk.
