The hard disk will almost be damaged resulting in data loss. To those of you who have not yet been granted, it is assumed that at some point in the future it will happen to you, so you must take your measures so that you do not lose your valuable data.
Let us begin by analyzing with as simple reason as possible, because it is almost certain to destroy the hard disk and data loss.
The hard drives we use in our daily computers are divided into two categories. The mechanical disks and Solid drive or commonly SSD as most of them.
Disks
The problem with mechanical disks is that like all mechanical devices wear mechanical wear. The wear is related to the moving parts of the disk but also the main parts of the disk where the data is stored. In addition to wear and tear due to time of use, there is also damage to vibration and falls which are of great danger to mechanical disks. In addition to mechanical failures, the PCB Board, the disk of the disk.
is not random, for example, that some computer manufacturing companies are trying on , specifically designed for Moving, adding vibration damping materials to the hard disk drive or even special programs that when laptop is open and works to be able to perceive imminent fall and place the read heads of the disk in "parking" state. In other words, transferring the read head off the disk to prevent as much data as possible.
SSD discs
The SSDdisks have been dynamically placed in our lives in recent years Because of the speed that they offer in the system. In fact our computer always had the speed simply the mechanical discs could not keep up with the speed of our computer. So today most of us upgrade our systems with SSD disks.
Unlike mechanical disks, disks SSD do not have mechanical parts. They are composed of electronic circuits and store the data in NAND flash memory chips that are capable of even after power failure.
Due to the lack of mechanical parts SSD disks are not sensitive to vibration and even falls. It is most likely a laptop to suffer other damage after falling and no damage to the SSD disk.
Certainly like all materials and SSDs Disks have their failures typically in the electronic circuits of PCB Board but also multiple times on the Nand chip that are stored our files.
Disks SSD are divided into different categories but it is not the purpose of this article.
SSD or HDD
Safely the technology moves forward and the option would be SSD disks, but it does not mean that they cannot present problems resulting in the loss Data.
What happens if the disk breaks? How do I get my files back?
As mentioned at the beginning of the article or time of the damage it arrived. The record's broken. What about the files?
For convenience we will split the damage to software damages and Hardwarefailures.
In the case of Software failures our files are not lost from the disk but we still don't have access to them. These cases are clearly easier to retrieve the data and about a high success rate and at relatively small and reasonable cost.
Various recovery programs are used in Windows or Linux depending on
Software failures do not require intervention on the inside of the disk.
In the case of Hardware failures things are more difficult and complex. Mechanical discs may require replacement of mechanical parts e.g. heads or even repair or replacement of PCB Board to access the data.
SSD Hardware problems have to do with PCB Board failures and sometimes Nand chip.
Due to the difficulty and complexity of these lesions decreases the probability of getting data.
As we constantly say to our customers the solution to ensure our data is to have backup. This can be just on an external disk or NAS or cloud services such as Google drive and One drive. In any case, however, our data must never be in a single storage medium.
