Votre disque dur est votre allié au quotidien pour sauvegarder tous types de fichiers. Seulement, vous n’êtes pas à l’abri d’une perte de données. Des documents ou des photos peuvent être effacés par erreur, un disque dur endommagé peut être défectueux. Quelle que soit la raison, vous avez Besoin de récupérer des données sur un disque dur. Chronodisk se charge de la récupération de disques durs.
Qu’est-ce qu’un disque dur ?
Les disques durs consistent en une boîte rectangulaire métallique avec au dos une carte électronique. A l’intérieur, il y a des plateaux magnétiques qui tourne à plus de 5000 tours minutes autour d’un moteur. Les têtes de lecture assurent la lecture des données.
Le disque dur rencontre quelques fragilités :
Le disque dur est la pièce la plus fragile d’un ordinateur ou d’un serveur. Cette fragilité est principalement à la partie mécanique du disque dur. Plus que toute autre pièce, ce support est soumis à des phénomènes d’usure.
What type of failure for a hard drive ?
Several situations can lead to file recovery on damaged media. Whether internal or external, the hard drive has mechanical parts. The latter are very sensitive to many factors: vibrations, falls, flooding, temperature variations, etc.
Lorsqu’on parle de pannes de ce type de support, l’on peut les classifier en trois types : la panne logique, la panne électronique et la panne mécanique.
Logical failure
The logical failure is the least severe of all internal or external hard drive failures. The media usually works normally, the only difference being that you can’t access your data.
It is usually caused by the presence of viruses in the software, excessive formatting, repartitioning, unexpected deletion of files,etc.
Electrical failure
In the case of an electrical failure the hard drive is damaged and does not respond. Generally it caused by :
The corruption of the firmware, the software, electrical damage caused by lightning, ect.

Mechanical failure
Concerning the mechanical failure of an internal hard drive, it occurs when the media is subjected to:
- shocks
- falls
- high temperature variations
- wear and tear
- flood or fire, etc
Voici les sons symptomatiques de la panne mécanique :
Defective heads
70 % success rate
Sounds from most to least common
Il se manifeste par des claquements (aller retour du bras de la tete de lecture) ou des bips
Heads do not respond
60% success rate
There is no head movement and the engine shuts down (Western digital)
Scratched trays
30 % success rate
This high-pitched hiss usually signals scratches on the disk tray(s) that prevent read/write heads from processing stored data.
Stuck engine
90% success rate
A buzzing or snapping from your hard drive may indicate a blocked or damaged pin motor.
Broken trays
0 % success rate
The glass tray is broken into pieces. In this case, all the mechanical features of the device are damaged.

Frequently asked question
The result of high-level computer technology, the internal or external hard drive is both complex and fragile. If it allows several types of documents to be kept, it is not immune to failures. Indeed, this support can be subject to any kind of failures that can affect your files and block their access. When this happens, you have a solution: use our data recovery services at Chronodisk!
Why choose Chronodisk to recover your hard drive folders?
We work on any type of disk, any type of format and configuration possible. Do not hesitate to contact us and entrust us with your work as soon as you detect an anomaly. Depending on the nature of your loss, we can recover your files with or without opening your external hard drive.
If it is a mechanical or electronic failure, data recovery is done via the opening of the media. For this, we have a clean room specially arranged, and equipment suitable for the work. For logical failures, we use specialized software to recover your documents from your damaged internal or external hard drive.
Our 15 years of experience in the field have allowed us to refine our knowledge in order to offer you the best services. Therefore, our technicians have no trouble quickly identifying the origin of the failure, in order to affect the appropriate data recovery solution.
Data recovery on hard drive : for who?
Retrieving documents on a medium concerns both individuals and professionals. In the case of professionals, losing important data about their company represents a huge financial risk. This can slow down the activities of the company and hinder its development.
Concerning the particular ones you are, losing files with a sentimental or professional value may also affect you.
In either case, data loss is not irreversible, and it is possible to recover it. At Chronodisk, we offer tailored services for every need. For individuals, our technical team is available 6j/7 to serve you.
For companies, we have an emergency cell available every day of the week, and 24/7. A crisis situation, crisis service!
Our advice to make easier the data recovery:
When your media (external or internal) is damaged, your documents are not permanently deleted. They are still there, but you no longer have the opportunity to access them. When the malfunction is such that your files are inaccessible, it is important to entrust the hard drive to specialized data recovery experts
To optimize the procedure and not reduce its chances of success, we recommend that you adopt good reflexes:
- In case of failure, whether mechanical, electrical or logical it is best to stop all manipulation on the external or internal hard drive. Do not hesitate to turn off your device or unplug your media.This will reduce additional damage and ensure the success of the operation.
- En cas de panne mécanique, nous vous déconseillons l’utilisation des logiciels de récupération. Ces derniers ont l’effet inverse, et aggravent plutôt la panne. Votre support interne ou externe est sujet à une panne logique ? Nous vous recommandons de ne plus utiliser votre appareil, au risque qu’il réécrive des données et que vous perdiez définitivement les fichiers inaccessibles.
Whatever the case, avoid repairing your device yourself, and entrust it to us! We have the tools, the lab, and the technicians to handle any damaged internal or external media.
Our services are accessible at affordable prices, to satisfy the greatest number!
Expert opinion: some technical difficulties on hard drives
Operating Shock:
The engine of a disc rotates at 5400 rpm, or even 7200 rpm. The heads are very close to the trays to increase the density of information. The slightest shock can create impacts, even scratches.
Scratch :
The slightest scratch on the disc can be fatal. The trays are made of aluminum or glass. The head flies over at 2 nanometers and the scratch has created overflows of material that are fatal for the reading heads. Sometimes, we can disable heads and read out non-insulated surfaces.
Tutos de mythos :
Vous trouverez pléthore de videos :
– changement de la carte électronique : il faut trouver la même carte et les cartes sont sérialisées depuis 2005 donc cela ne fonctionne plus.
– ouvrir le disque dur et changer la tête de lecture (sans salle blanche qui empêche la poussière, c’est un peu la roulette russe)
– le mettre au frigo une nuit (une belle légende urbaine, si c’était si simple…)
Le danger d’une mauvaise intervention
Ne confiez pas votre disque dur à n’importe qui !
Le voisin GEEK ou les dépanneurs informatiques ils sont toujours de très bonnes intentions mais malheureusement peu ont vraiment les compétences. Ils n’ont pas conscience du danger qu’ils font porter à vos données.
La récupération de données n’est toujours pas enseignée dans les formations classiques.. Le risque, c’est qu’une mauvaise manipulation détruise toutes les chances de récupération. Les laboratoires font des exploits mais pas des miracles.
Nous constatons tous les jours des ouvertures “sauvages” de disque dur hors salle blanche, des disques durs qui ont trop forcés (destruction des surfaces magnétiques), des cartes électroniques inversées, des composants manquants !!!
Demandez bien à votre prestataire informatique : ce qu’il va faire et comment. Si les réponses sont évasives, envoyez nous directement votre disque : vous doublerez vos chances de récupérer vos données.
Vos priorités de récupération :
Ce sont les informations des éléments que vous souhaitez récupérer :
Le type de fichier : par exemple 1/photos 2/Documents 3/Comptabilité
Leur emplacement : Partitions C:/photos/ D:Sage/comptabiltié
Pourquoi il est important de connaitre les priorités pour nos techniciens ?
Nos procédures sont strictes : ils commencent toujours pas copier les données prioritaires en premier puis ils copient l’intégralité du disque. Sur nos documents, il est malheureusement souvent indiqué TOUT !
Si le disque se raye en cours de lecture, il vaut mieux commencer par les bonnes priorités.
Plus vous êtes précis, plus les techniciens sont performants.
