Pour que vous ne soyez pas surpris par une défaillance, vous devez être attentif aux différents signes de dysfonctionnement du support. En effet, même si ce dernier peut s’arrêter brusquement, il existe parfois des symptômes de mauvais fonctionnement qui apparaissent au fur et à mesure, et qui annoncent le dégât que subit l’appareil.
Strange noises
One of the warning signs of a hard drive failure is unusual, strange noises. After a shock for example, it can happen that your equipment emits squeaks or sizzles, sometimes at a very high rate. When it’s the case, do not hesitate to contact us as soon as possible.
The faster you react, the more likely we are to succeed in the data recovery procedure.
Disk errors
If you realize that some files disappear from your hard drive, or if it displays errors, this may be the sign of a failure. This can be a programme that suddenly stops or documents that you can’t find anymore, when they were previously saved ect…
Unable to access the disk
You can also recognize a malfunction, by the fact that your storage media works, without you being able to access your files. In that case, the equipment in question does not emit abnormal noise and the defect is generally internal and invisible.
A burning smell
It can also happen that your hard drive emits a strange or unusual smell. If you smell a burning smell on your rack, then it may be a breakdown. In this case, you need to react quickly and appeal to professionals, so as not to lose all your important files.
What are the different failures of a hard drive ?
Because the external or internal hard drive is not infallible, it can suffer various types of failures. When this is the case, the data recovery method depends on the nature of the damage and its significance :
Logical failure
Logical failure is usually the least severe that can attack a hard drive. Indeed, the equipment continues to operate without you having the ability to access your files. It is usually caused by human error (bad formatting, unexpected deletion, bad repartitioning, etc.).
Data extraction when this type of problem occurs, does not require a clean room run. A data recovery software is enough to overcome the malfunction.
Electronic failure
With regard to the electronic failure of the hard drive, the main causes are electric shocks (power surge, lightning, etc.). As a result, the device stops working.In this case, it becomes urgent to troubleshoot the electronic card before proceeding with file recovery. Troubleshooting takes place in the clean room, to ensure that the procedure is carried out in good conditions.
At Chronodisk, we have a well-equipped laboratory to perform all the work of extracting your important and confidential elements.
The mechanical failure
The hard drive mechanical failure is the most severe, or severe. It usually occurs when your media :
- Suffered a violent shock
- Fell
- Is worn
- Suffered from fire, flooding, etc.
In the event of a mechanical problem, all functions of the device are damaged. It must go to a clean room, for disassembly and replacement of the reading heads.
