Data loss can have two origins: hardware or logic . In the latter case, the error is very often human: formatting, deletion of files… Sometimes, this deletion is not the result of Data Recovery an unfortunate manipulation, but that of a deliberate and malicious act (you have without you’ve probably heard of ransomware before).
Anyway, the chair-keyboard interface is behind it all. But however gross the error, however virulent the virus, all that can be inflicte on the hard drive is a logical failure, i.e. data corruption, with no possible damage to the hard drive itself.
If the ransomware problem is to be treat separately (without giving in to blackmail…), the problems of file deletion, partition or untimely formatting can be solve by specialize software. If you want to know more about this, do not hesitate to consult our file: recover lost data: tips and software .
If you don’t feel comfortable with this kind of software or if you have the slightest doubt about your breakdown, there are good, competent professionals who will be able to recover your data. But beware: whether you go through a third party or take care of the operation yourself, if the failure is hardware, any rescue attempt via software could jeopardize your precious files. In order not to be mistaken, it is important to make the correct diagnosis as to the state of your hard disk.
When carrying out the diagnosis, a precaution of use is essential: it is a question of supplying your hard disk for as short a time as possible . Indeed, if the problem is mechanical and affects the read heads (this is often the case after a shock), the rotation of the platters can seriously damage Twitter data which was perhaps, until then, intact.
If it is a hard disk place in a portable PC, turn off the latter quickly once the diagnosis has been establish. If the hard disk is from a tower and is not the system disk, it is better to extract it and place it in an external rack or dock, so that you can turn off the power in an instant.
Those, first of all, where the hard disk no longer spins and emits no sound (most often electronic card problem, more rarely motor problem), or those where the disk spins for a while before stopping its activity (this shutdown is an automatic disk protection maneuver that avoids data corruption in the event of a recognized malfunction). In both of these cases, you cannot act on your own, but fortunately, you cannot make the problem worse either. It’s not always the case.
